Don't use carphone warehouse they are just conning people. I have been with them for years all been well and good until October last year and my upgrade was due. Guy phones me I wasn't to well at Time told him I wanted to go sim only to reduce my bill ends up talking me into a £35 a month contract which has ended up costing me more as not receiving what he said I would and have had to add bolt on. Kept my old phone too said I would receive £290 cash back!!!!! Have I heck as like still not received keep phoning them can't hardly hear what Advisor says as sounds like load of girls/kids screaming and shouting in the background so impossible for me to understand what being said to me as can't hear basically. Am now considering just not paying my bills and going elsewhere as not upholding their part of contract and even though ask to talk to manager they just frob you off until in the end you got no choice as cannot hear/understand them. So yep I have resigned myself to fact they have conned me
