iTunes being rubbish

[Lewis.]

My card thing wont go through. Want to redeem it but it says it's not a valid code. Checked it about 10 times. Is it a known problem or should I take my card back?

Might be that the cashier didn't activate it properly - they only work once they have been

That's what I thought. He didn't seem like he knew a lot about it all and I think he was a trainee. He asked the woman on the till next to him and she just gave him a shoulder shrug. This is in GAME store. I'll have to take it back. I'll give it a go a bit later though as I remember last christmas I got a few itunes cards and none of them worked - however when I tried them all again a few hours later they all worked again.
