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!

This company has mis-sold a 5 year broadband and telephone contract extension to my 81 year old father in law that we have only just discovered he verbally signed up to three years later (as we now have access to his accounts). This was as a 'contract review and renewal' call 2 years into a previous agreement. We have the recording of the call where he twice states he does not want to renew and clearly not fully understanding the service but is then talked around by the agent. The price he is paying for this service is over double what BT or any other provider charge. The agent has no interest in his needs and whether this is suitable for him - my father in law even questions whether he should sign up for 5 years given his age and health, at which point the agent states that if he dies they will not come after his family for the rest of contract - "We are not cold" he states!!! All they are interest in is signing up to another 5 year deal which itself is against Ofcom rules. AVOID THIS COMPANY.

A deliberately deceitful company. Reached the end of the discount period (18 out of 36 months) only to find I do not get another discount but extortionately high bill for the remainder. The alternative is a new contract for another 36 months approximately 4x the tariff of competitors (egO2). Truly awful

As with a lot of the other reviews here sold a contract over the phone expecting 3 years at quoted price after refunds,not once was any mention made of the fact that discount was only for 18 months and after that you are paying ridiculously over the odds for the rest of contract,will have to suffer it but I have nothing but contempt for this company.Avoid at all costs
