i have spent all day putting up a wardrobe for my daughters bedroom, felt so proud when i was putting the doors on because i had done it myself,,,, bummer, they have gave me the wrong screws to put the hinges on and they have come through the side, got to dismantle and take back, only to have to start again...
Retrospect- a wonderful and yet highly annoying thing!
Take it back and tell them your tail of woe in an e-mail,you never know,they might send you a coupon to cheer you up!
I wouldn't have queried it either if they were in the pack.
I still have a half built filing cabinet which has been lurking for waaaay too long now, couldn't even get the screws all the way in, even with a power drill!
