He left a comment that the key did not work on the same day that it ended. So, thanks to your records, we know that the game was not free at that time.

You are right though, the timing is annoying that your giveaway ended just before the date of it going free. Nothing wrong with that - but your comment was a little suspicious, it ended on the 5th, and he commented on the 5th, then on the 6th you told him he can claim the game for free for the next 48 hours. If a winner has a problem with your key, you should try to find out what that problem is, rather than just say he can get it from somewhere else.

Anyway, the winner has not replied. My advice to you would be to email the winner directly. Explain the situation, and ask if they agree to delete. If they agree, send a screenshot of the email conversation to us with your ticket.

Thank you, have a good day
