One of Wandsworth Southside Carphone's staff, (girl, called Br...) was very rude, very unhelpful. the whole service was misleading I had to return the phone. They forgot to mention I will receive a sim card (that I never asked for and it was a completely different network). On returning the phone that credit just vanishes as the value on it non refundable. I was not able to keep the sim card. The girl handling the situation was awful. then she went to the back when I caught her saying something like 'bitch' to her manager. It is her luck I was in a rush but I wanted to report the whole thing. Very bad service, I will never go to a Carphone Warehouse again.
