Windows on Xbox 360? Redeemed code buy 1 month membership how to?

A recently purchased a gold membership for 1 month but I unfortunately I can't play online as it asks me for a 25 digit code.... However I haven't received that code? How do I redeem the code to find out what it is? This is for xbox 360

You have to redeem your 1 month Xbox live membership code

I too have received the same thing but instead of a 12 month Live Gold which it states. The code says its for a 1 month Live Gold.
