When I checked my balance on my mobile phone, it is now £3.32. I had £5 exactly and I never even touched my phone for days except taking 3-4calls, not making them. After a while, I checked my balance again and now it shows £4.12. What is going on? I got an O2 message saying they will take £1 off my credit for the data usage i've used today. I've never even touched the web or anything that uses data and if I did, I would have used my Wifi. ( I did connect to my wifi once or twice). This never happened to me before and it's on my Blackberry Torch 9800.
Does anyone know whats eating up my credit and why it showed £3.32 at one point and then later £4.12?
