You and I are stuck in a pickle, and I can't help you.
Scammed me a key that didn't work. The temporary fix did not work, and I did try. Doesn't want to give me a refund now and I'm stuck in a "pickle".
If I get my refund for what did not work, I will gladly remove or lock or whatever can be done to erase this.[/s]
The above has been solved. Leaving it there for reference.
Report Edit: I received 30 keys as a "refund". None of them worked when redeeming. They seem to have been working using a check of some sort, but were probably flagged and made not redeemable by Microsoft somehow.
