We joined talk talk after being told by the sales rep in carphone warehouse, that talk talk would take care of all our problems with Bt, and there'd be no charge to us. This seemed to be going fine, as we recieved a bill for £0 from BT, then the next day we recieved a second bill for £137 as apparently we were under contract with BT and talk talk should have told us that there could have been a possibillity of this happening, but they are too intrested in making a sale. We are now in debt because of talk talk so be careful what you are actually signing up too and make sure your not under contract with BT
