For the past 12 months I've been having trouble with phone service and data connection, regardless of where I was. Most of the time I was in either London or Portsmouth. I contacted 02 over 60 times in emails and phone calls, not one of my emails have been responded to up to this day. But I recieved automated emails saying that they was recieved and someone would be in contact shortly, but this never happened and still hasn't happened. I phoned 02 multiple times over the past 12 months, and each time they all did the same thing, they reset my phone but because after a reset, you need to turn your phone off and then back on. That ended our call and of course, no one ever called me back. So I would have to phone 02 back and start again from scratch with a different agent, who would say the only thing they can do is reset my phone. A month ago I spoke to someone on the phone and said I'd like to leave 02 and cancel my contract. They asked me why and I explained the signal and data connection problems I've been facing over the past 12 months. They said they would send me out a new Sim card as it may be the 02 sim card stopped working, as this can happen. I agreed and one was sent out to me. After receiving the new sim card, I inserted it into my phone only to find it didn't work. I tried to contact 02 but was on the phone for over 40 minutes in a que, in the meantime, I had the phone on still but I travelled to my nearest 02 shop. Only to find the shop has been closed down. Still no answer from 02 throughout my entire journey. I went into another phone service provider to ask them to take a look at my phone. One person from their technical team looked at my phone and the brand new sim card and informed me that the new 02 sim card sent out to me is faulty. They never tried to sell me their products their or sway me into leaving 02, they just informed me that 02 had sent me out a faulty sim card yet again. I then emailed 02 to explain the situation but to this day, no one from 02 has acknowledged or responded to any of my emails. Over 60 emails. It's very disheartening to know that they their customer service and communication is this bad, especially as their phone company and are supposedly meant to provide communication.
