Last year I decided to get a mobile line contract and I approached my local carphone warehouse which is in Brent Cross shopping centre. I managed to get a contract with Vodafone. A very kind salesperson who was looking after me that time was very kind as he rewardad me with 2 new other phones not knowing there is a catch after. He said since it is an offer contract I was given 2 other cheap phones as he it is apparently a gift package with the contract I had. Lately, just last month, I had a credit history report saying that I owed money to carphone warehouse due to a line with that has not been yet paid. I was shocked, I went to one of their branch and explained the situation. I also found out from the branch that it's not only 1 line but 2 other lines were remain unpaid. I was extremely upset as I wasn't aware that those phones they gave me for free wasn't free in fact they were billing me without my knowledge. I was advised by the staff of carphone warehouse to contact the complaints department via email. I then send them a email of formal complaint and on the first response they said they have raised this to the branch where the sale was made and I should receive a response within 3 days. It's been 1 month and still no responce from the branch. I have been in contact with them for so many period of times and they are giving me the same answer which is to hear from them after 3 days. It is very disappointing and it is tiring they are giving me other option to seek legal advise now. Carphone warehouse CEO you should action immediately! Your reputation is in reliable. And your customer service is utterly poor!
