Rubbish! Signed up for an s5 contract, queried why I had been given s4 charger with it and was told to send back which I did. A week later I had to contact them to find out where my new charger was only to be told it was the right one all along and my charger had been posted back - not that I received it for a further 2 days so I couldn't use phone for over a week and they couldn't even be bothered to contact me I had to chase up. Also bought through top cashbook website and surprise surprise haven't received the cash back either!!! My advice - go somewhere else.
