I have been with 3G for 9 years on various contracts as and when they needed renewing. I am 18 months into a 24 month contract and they have increased my monthly bill by about 5%. Customer services said they are allowed to do this once a year if they wish as it is in T&Cs, which I cannot find 18 months into this term. Anybody know if they can do this? Time to switch providers I think.
