Absolute joke of a company Would give 0 stars if I could Don’t even know where to start , called me and offered to pay me out of my phone contracts . Waited for phones to arrive which was late , then im cards arrived a week later Then they didn’t work And too top it off they haven’t paid my old contracts off and £850 has left my personal bank to pay for my old contracts off. Now got another £1000 bill to pay with vodaphone Worst company I’ve ever dealt with , ignore all your emails , won’t call you back Don’t even waste your time

!!DO NOT DO BUSINESS WITH THEM!! Absolutely disgusting practice! If you have only just signed up with them please carefully check your contract and end it asap if anything dosen't sit right. Their contracts trap you and there is no way out! I have to pay £1000 over the odds to have the privilege to leave, as do thousands of others. Please google 'OneCom miss sold contracts' before signing up. Many people's mental health has been effected by this company

Written Assurance Not Honoured and Complaint Not Resolved I am disappointed with my experience with Onecom. Before entering into a 36-month Vodafone contract, I raised concerns about the cost after the initial discount period. I received written assurance that my account would be reviewed after the discount ended and that Onecom would work with Vodafone to look at reducing the monthly cost if I did not renew. After the discount period ended, I contacted Onecom expecting this review to take place. However, I was advised that the only option available was to enter into a new 36-month contract, which was not what I understood from the original communication. I raised a formal complaint and provided the relevant emails, but I feel the main issue has not been properly addressed. My complaint has also been handled by different advisers, which has made the process frustrating. I hope Onecom reviews this matter fairly, but based on my experience so far, I cannot recommend their service.

I am 76 years old and this is the worst company I have ever had the displeasure of being involved with. For the last year of my "contract" with them, I was paying £64 for a sim only service. They will trap you into contracts with payback clauses that they will honour until you do not wish to renew with them at which point the legalise kicks in and you will be stung. My contract was with Vodafone and I have no idea how Onecom got to take it over, particularly as it is a private, rather than business phone. Just avoid these people like the plague.

Stay clear, absolutely disgusting firm. I was under the impression that I could cancel my phone contract after 18month. Turns out I can only renew and if I don’t renew I hv to pay the full amount every month which is £124 for 2 sims for 18month as it’s a 3yr contract. At this moment in time it’s £62 with cash back that only last 17 month. It’s in the small print by all accounts. Do not sign up with these at all costs. I’m now going to hv to swallow these extortionate prices now for 18 month. Bare in mind u can get 2 sims unlimited everything for £30 or less per month

No customer service charge over the top monthly amounts, don't take anything into consideration, all they care about is getting your money. I would never recommend. Please do not use you will regret it!!! I would have considered staying as a customer if they were fair but unfortunately that isn't the case. Very disappointed

I strongly advise against entering into any contract with OneCom. Despite presenting themselves as a communications provider, my negative experience has been that communication is largely one-sided and not in the customer’s favour. We weres persuaded into re-signing a contract we had intended to exit, through the use of complex and unclear language during a phone conversation. We were then held to ransom by those verbal agreements at significant financial cost with legal action threatened. We would caution others to avoid agreeing to any contractual terms over the phone, particularly where details are not clearly set out in writing. More importantly, I recommend thoroughly researching reviews and customer experiences before engaging with this company at all. Learn from our experience—do not make the same mistake!! It will cost you dearly!

We recently acquired a new company and, as the new director, I contacted Onecom. Under the same conditions—5 phone users and a faster fibre internet package—we were able to obtain a quote of £103 + VAT elsewhere. However, the existing contract is valued at £212 + VAT, which was signed by the previous director. Although we have requested assistance, no one has been willing to help. This company appears to prioritise its own interests and shows little regard for its customers. The terms offered seem to be entirely in line with their own benefit. I would strongly advise staying away from this company. Their prices are very high, and they do not appear to value their customers. I have never encountered such a disappointing experience with a company before.

Absolutely shocking experience with Onecom. We originally signed our contract with Dalys, but since Onecom took over, it’s been nothing but downhill. Prices have doubled while the level of service has been cut in half — completely unacceptable. I’ve now tried four separate times to cancel our contract. Each time I’ve either been left on hold for an unreasonable amount of time or promised a callback that never happens. It feels like they’re deliberately making it difficult to leave. Poor service, poor communication, and zero accountability. I would strongly advise anyone considering Onecom to think twice.

They operate on an aggressive pricing increase strategy to lock you in. Think twice if you're considering a business contract. SIM-only price jumps to £80+ unless you re-sign for another 36 months. Vodafone sells comparable plans for around £30–£40, yet the “standard” price here is over double unless you commit again long-term. Proceed with caution. Onecom will say it's contractually allowed, but the issue is the coercion - pay less again by renewing or pay far more than the market price for a SIM (I've researched and it absolutely over double market price).

They are unscrupulous thieves, not only was I paying them over £70 a month for a mobile contract that I now pay £3.25 a month for a better deal but then they decided to charge £ 10 a month for dark web protection, I emailed that if they dared to charge me for it I would complain to ofcom and heard no more but it now turns out they have charged me for it this last year so complain I will and I will also try and get my bank to claim back some of the money as I have been scammed,if I had the money I would sue them as they all derserve to be jailed

Feedback on Onecom Service Experience I want to share my experience with Onecom so that other small businesses can make informed decisions. I strongly recommend you do not enter in to a contract with Onecom under any circumstances Background * I was cold-called by Onecom and persuaded to sign a three-year contract for five work phones. * I was assured by their representative, Gareth Duggan, that I would incur no termination costs, great customer service and no downtime to my company Key Issues Encountered 1. Unexpected Termination Fees * Despite repeated requests for confirmation of costs, I was charged £1000 more than quoted when I needed to end a previous agreement. Why would I get a new contract and pay for it - completely tricked over the phone by a slimy sales man 2. Service and Signal Problems * I was advised to move to Vodafone with a guarantee I could switch back to EE quickly using eSIMs and with no downtime, if signal wasn’t adequate * After reporting poor Vodafone signal within days, my concerns were not addressed promptly and I was ignored for days * The transfer back to EE took over a month, causing significant disruption and lost sales. * At one point, when we finally moved back to EE my primary EE line was down for a full week - they refunded me £43.20 but nothing for the previous month and no where near enough to compensate the loss of sales. 3. Customer Support * Promises of ongoing assistance were not met. Emails to Gareth went unanswered, and I was told the issue was “not his department.” This was not the half of its. No one cared or knew what was going on and it got completely out of hand with the amount of people I called to try and get a response 4. Future Contract Concerns * I have been informed that if I do not renew with Onecom, fees for the five contracts will rise significantly, creating ongoing financial strain and entrapment for the for years to come as I will not be able to pay the termination fees as it will cripple my business. Dispute Resolution Attempt * I escalated the matter to CISAS, but the adjudicator’s report did not address the core of my complaint about verbal misrepresentation and I am now left to go to small claims court or ofcom. The above doesn’t even cover all the issues there are too many to state. DO NOT ENTER IN to a contract with these people.

I will take to court so if anyone want ls to join me let me know
