Last summer I changed from pay as you go to a monthly plan and added on a new phone, Sony xperia, and I'm billed an additional £5 per month for the phone. I'm aware that if I wanna upgrade now, it will cost me £80. I don't have much money at the moment, but my phone is playing up a lot recently. I had a call and needed to select an option, but the phone screen froze when I tried to enter the digit, the only way to unfreeze it was to turn the phone off. It turned off after a few attempts! Then when it was back on, I couldn't receive any calls, they diverted to my answerphone. At the moment, it's working again. I've been having lots of issues like this recently. If I take it to an 02 store, will I have to pay for a repair and how do I show them the problems when it's an intermittent fault?
