T-Mobile too mobile!

Isn't it typical? Just when you think you have a pleasant day ahead with nothing to spoil it, something does. My mobile phone bill arrived and was inexplicably high. I have been with T-Mobile since they started and am on a very good deal with a loyalty discount. Recently, I went into my local T-Mobile shop and was awarded a phone upgrade so long as they could sign me up for another 18 month contract. I agreed, as long as I could stay on my present contract, which is a manageable amount each month.

Anyhow, I just rang them asking for an explanation, only to be told that the cunning sod in the T-Mobile shop had changed things on his computer, so my current cheap deal ran for one month only, and then I was switched to a much more expensive deal. The unhelpful woman in customer services told me I would have to take the bus into town and take it up with the people in the shop. Yet she could have put things right just by tapping a few digits into her computer. I am steaming mad. Mr G says they have broken their contract with me and I am free to go elsewhere. I hope this is true. He has a good deal with Virgin and only pays £10 per month. I have checked the contract they gave me in the shop and there is no mention of my payment plan whatsoever. Whatever the outcome, my peaceful Sunday is now ruined.
