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.
