Q: I aggresivley scratched the redeem code off of my itunes giftcard. What to do ?

Your question has nothing to do with itunes U - where Colleges, universities, and museums post educational content.

Try posting in  an appropriate forum.

If you use the search bar at the top of this page by "Support" you will find:

iTunes Store: Invalid, inactive, or illegible codes

Yes I followed that link and it asks me to type in the activation code ins full I only have part of it left

Not really helpful that link

This remains the wrong forum for questions about using iTunes cards or otherwise general use of iTunes. And you replied in a thread that's almost two years old.

Anyway, if you read the support article completely, it tells you want to do if you can't read part of the code.

Regards.
