Thank you very much for help. I did post a letter in early November and I also faxed this letter. Ten days after the sending the letter I did manage to speak to someone who told me that the complaint was being dealt with. A couple of days after this I rang 6 times but I wait in a cue and then it rings again. I did ring network 3 who have also logged my complain, they told me that they do not deal with the mobs.com or mobile solutions as it is also named but they have also asked for an explanation from the company. I cannot believe that these companies can get away with what they are doing. They owe me £165 which should have been paid in october, but unfortunately my contract does not run out until April when I will again have to send in the voucher to claim by other £165. I will let you know how I get on. Thank you once again for your help
