During a sales call with O2 in January 2023, the agent repeatedly told me to ignore the pricing sent to me in a contract, and assured me the price they verbally told me was correct. Later, it emerged that I had been manipulated into signing the contract in the belief it was not true, when in fact it was. I was then charged more than double the verbally assured fee every month. I called, emailed, sent private Twitter messages, and attempted to use O2's messaging service to correct the problem, but was rarely able to get through. Agents promised to listen to the initial call recording and get back to me but then never did, their systems were often down, the messaging service was broken, or busy / unavailable, they responded to not a single one of my many emails, and 3 months later I'm still being charged double what was agreed. I can't get a response from O2 despite them being in breach of contract and being protected by the consumer rights act and am locked into a contract that will charge me more than £1000 over what they told me it would be. I've tried to cancel multiple times, but they keep saying they want to charge £500 to exit, despite it being their lies that made me sign. If you use their messaging service and they ask a question, when you reply it starts the whole sign in loop again, and then it's often busy and they won't put your message through. I think I've tried this more than 50 times over two months and have spent more than 5 hours trying to get through on the phone.
