My contract was due for renewal so wanted a sim only deal and went to CPW. Very helpful. My network was Vodafone, was told still best reception price £13.50 - OK. Said had to sell me an 02 sim because Vodafone would not change to sim only therefore have to do a 3 port procedure to keep my number (gave me a sheet to help), Rang Vodafone to start the process and they queried why I was doing this, said CPW have lied to me and they could swap so I did this direct and have since tried to cancel the original one, Went to shop and they said could do not do this, rang cust services and told the same. Rang Vodafone to try and cancel the sim from CPW and they said they are not allowed to do this. Don't see why I should trek into Manchester again to shop to be told no. Very reluctantly going to do the 3 way port procedure. Will not use them again.
