As a paying customer I’ve had the worst experience and arrive from o2, from them over charging me to constantly blocking my phone. So much confusion between the staff, messing with my credit and in general just giving me hell. I’m not the only one who has had negative things to say about their service. Wanted to know if anyone has taken legal action or experienced the same. I for one will be taking legal action. As I speak my phone has been blocked for days and I have no way of getting into my o2 to even chat to them because they blocked that too. They owe me a large some of credit on my account and it shouldn’t be blocked. I’m really fed up. The site isn’t even user friendly where I can chat to someone without being on the app. I’m exhausted. This has been going on since November. I’ve only had one month of use of my phone as they are always blocking it and apologizing at this point I’ve had enough.
