Thanks for the replies so far. I didn't make 17 different calls, just the one but had to say 17 time 'please tell me my Pac code. They started with 'may I ask why you want it' I replied, NO. They then tried 16 further times to find out why I wanted it, what they could do to keep me, why it was bad to leave etc etc etc. OK, back to my actual question. As far as I can tell from the limited replies so far, THREE do not have to tell me where my credit has gone. So, I have gone - elsewhere!
Guys. I am with THREE (not for much longer) on PAYG. I hardly use the phone at all for anything other than receiving calls and the occasional text or call out. The package is the 1,2,3 so is very cheap and a £10 credit usually lasts me months. I topped up on 24 Jan and that would normally be it until maybe May or June. But yesterday I received a text from THREE asking if I want to top up. The balance was £0.59 Now I know I have not used it and I always have mobile data switched off, so wanted to know where Three has used my money. I logged into my3, but as I am PAYG
