Sounds like I've received a refund now and no sign of it being resent, annoyingly waited a month for the case and now just have a refund of about 1/2 the value needed to buy it elsewhere.
Royal mail, sent on the 27th apparently, which is close to the time I phoned up and complained for about the 4th time.
Was it courier or Royal Mail?
Actually I tell a lie, I've just received the order and a refund...
