I'm in the process of selling a phone with them, when I sent the details it was for the wrong GB size, I have since tried to contact them to amend it and no response from email, live chat, or call... On hold for 10 minutes then hang up on me.Hopefully this can be sorted outEdit: managed to get through on the phone will update when it's all processedEdit 2: all processed and awaiting payment, was hoping to get it before the weekend, but it appears like it'll take the full 7 days to get to me
