Was so mad that I snapped the card in half and will never buy anything from them again without them checking it infront of me (Yes I had a reciept and could have returned it, but they would say I gave them a fake or worst they will take it and stick it back on stock to sell to someone else, that is why I snapped it in half).
You could have at least given them a chance to rectify it, Ive had pretty great customer service whenever Ive had to deal with them.
The Birmingham branch have great staff and a smallish selection of mostly older games but at pretty good prices. Mainly use them to get rid of old graphics cards and stuff that I can't be bothered to put on ebay.
