I haven't been able to pay mine to o2 these past few days, went in to the bank to see what was up and it's nothing at their end, and apparently they'd had a load of people in today saying they couldn't pay their mobile bills, but all from different networks.

Can't pay it in the o2 shop either, and ringing them up doesn't work, and I can't anyway because they've cut my fucking phone off. cunts.
