Anybody had anything like this? I ordered a pre-paid card with xbox live points, it arrived this morning after 8 days (pretty long for play..) And its been used? the silver foil scratched off and the code invalid? I'm looking for a number for play, I don't want to have to wait and argue over a chain of email really, but obviously not happy. No order page page in the package either, not sure if there's supposed to be some kind of in-voice withe everything they sell but gives me doubts with the postman.
How likely am I to resolve this? How am I supposed to prove I didn't use this :S
