Hello MiracleIsHere.

Deleting the giveaway does comply with our rules, but just to make you aware: you are not required to give your permission. Let me explain the options for situations like this so that you will know where you stand.

Whenever a winner (you) is having issues redeeming their won key, they should always first leave a comment on the giveaway to explain the situation to the creator (which you correctly did). After that one of these things can happen:

1. The creator provides the winner with a new key that the winner can redeem.
2. If the creator is unable to provide a working key, the winner can mark the giveaway as "Not Received" when they are able to do so.
3. The creator and winner agree to have the giveaway deleted. For this to happen, the creator needs the winner's permission but the winner has no obligation to agree. The default when a winner is unable to redeem a key is to mark "Not Received," deletion is completely voluntary courtesy.

Now that you've been made completely aware of the situation, how would you like to proceed? Either option is equally fine from Support's view, it is entirely up to you which you prefer.
