I don’t really know what went on behind the scenes, but my iphone has been returned to me by Carphone Warehouse. I got a call from the manager saying that they’d had a call from the headquarters and it was all sorted, all I had to do was go collect it. Which I did. So thanks if you had something to do with sorting this out behind the scenes, or maybe it was just lucky or sense prevailing. Still, it shouldn’t have happened and I’m going to be asking for some compensation… will keep you posted.
Off to set up my new phone!
