Purchased a Win 10 Pro key. Waited 13 days until claiming he never receive the key which was emailed to him within the hour of him purchasing. I sent the key through email messages so he had it for sure. He then told me that the key was "too old". After that, he wouldn't respond to any messages until he could escalate the case. Even though I had verified proof that he received and used his key, he got the refund anyway. Called PayPal and they said that the money back system doesn't apply to email'd items and that I will still get my money.
