On holiday in Thailand, I kept my phone in flight mode throughout my holiday, or used hotel wi-fi... . Except for one inadvertent internet session in a restaurant three doors from my hotel lasting, at a guess, approximately 30 mins (thought I was still connected to hotel wi-fi, nothing on the phone to tell me otherwise until a text message arrived to tell me the cap of 50 euros had been applied, for which I was grateful). Annoyed that I'd spent £40 unintentionally, and cursing myself for a fool, I put the phone back into flight mode. Needless to say, when the bill arrived (from Utility Warehouse, but I suppose it could be anybody) it wasn't £40...it was £754! I put in a complaint and the response is to reduce the charges to £300, which I actually think is quite reasonable... But I thought I'd see what others think before I accept - any ideas?
