I had a phone delivered to my address by Citylink which was not addressed to me. I immediately phoned Citylink to report it and was told that this is a phone stealing attempt. Carphone Warehouse in this case but all phone shops are asked to supply a phone either by phone or email. After it is delivered a person knocks at the door claiming to be the person it was addressed to and says he has been told it was sent to the wrong address. If you hand it over you will eventually be asked for the cost of it and have your credit record damaged. Fortunately having been warned not to give it to anyone not wearing the Citylink uniform I told the person who came for it that it had been collected for return to Carphone Warehouse. Citylink were very interested to be given the car registration of that person. Be warned it could be you next time.
Citylink have contacted me and it appears that Carphone Warehouse staff get a commission for every phone sent out. They do not appear to make any checks on the supposed customer so they are obviously getting the phones at such a cheap rate that they are not bothered by it.
