There are entire sites and facebook pages detailing how awful this company operates. They signed up my eldery 78 year old father for a 5 year business contract. Absolutely evil.

Avoid at all costs....these people need closing down - they are scamming small business owners - now trapped in a 3 year deal that is double what I wanted to be paying in the first place - due to ridiculous cancellations fees!

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.

Diabolical company. The list is endless Sold a 3 Yr contract now saying 5 Said an amount billing me more....can't talk to anyone that knows about accounts, say credits are raised....the amounts change daily but are never received. Asked for a copy of contract call and 2 months later still won't let me have it. Said I would have Microsoft in the package now saying they had made a mistake....now when I call the office they don't answer. As I have complained they won't answer emails either. I will take to court so if anyone want ls to join me let me know

I regret ever moving to Onecom. I was contacted by their sales agent and told I had to upgrade due to the BT ISDN switch-off. I was promised my new cost would be within my current costs and on a 36-month contract. That turned out to be completely untrue — my bills jumped by more than 50% and I was later told my contract runs until 2030. When I challenged this, Onecom refused to take responsibility. I had to chase them for months, sending countless emails and calls, while they insisted everything was “as agreed.” Only after I reviewed my own call recording did I prove the sales agent had misrepresented the contract length and costs. Even then, they dragged their feet, ignored deadlines, and failed to call me back despite repeated promises. Their own complaints manager eventually admitted there had been misrepresentation and poor service — but it took me months of stress and persistence to get that far. As of today, I am still waiting for a fair resolution, including a refund for the overcharges. This company has shown mis-selling, poor complaint handling, and a complete lack of transparency. If I hadn’t had my own call recordings, I dread to think how much longer they would have denied everything. I would strongly caution other small businesses to avoid Onecom — read their reviews and you’ll see this is not an isolated case.

Just awful, I ordered a SIM card for the 24/10/22 and the delivery failed to turn up. I rearranged the delivery for the 28/10/22 and they failed a second time, when I phoned to discuss the issue the agent hung up after struggling to answer difficult questions.

I have to agree with all of the other terrible reviews on this site. STAY AWAY FROM THESE CON ARTISTS! They pull you in with absolute bullsh*t over the phone, telling you how little you'll pay per month for your contract, only to send you something in writing that is completely different to what you were told verbally and making you pay money for things you were never told you would be paying for. STAY AWAY!!!!

They ruined our small business by using misselling practices, and use the lack of protection and call off periods to trap you in contracts, working with Vodafone to scam you with your mobile contracts. Sickening business practices.

When I got pulled in by one com they told me that my monthly bill would be £36 a month and yet they instructed Vodafone to take £97 a month. What they are paying Vodafone is minimal. If everybody is paying around the same date as me, which is around the 1st of the month, I then get refunded 15 days after they have taken the £97 I get £58 refunded. So for 15 days that £58 is sat in their bank earning interest I know it’s only £58 but times that by 1000 people and that’s £58,000 these figures are only a example but could be more as I know people are paying more, is this what the scam is because it is impossible to change the direct debit date closer to the refund date. Have tried to change the date but they say only Vodafone can change the date but on speaking to Vodafone they tell me they can’t change the date it’s only One Com that can change the date which they will not do as they want as much time between the date we pay and the date we get refunded.

Awful, awful company. AVOID AT ALL COSTS. I tried to get a phone line switched to my company name. No problem, they said "it is all done for you". Four weeks later they cut off my business phone line. They said they had forgotten to tell me that I needed a new router and had forgotten to send me one. They are a bunch of clowns that can have a very negative impact on you and your business. AVOID! AVOID! AVOID!
