Without making any accusations, that sometimes happen when people traded/regifted a win and then realised they couldn't enter SGtools protected giveaways because of an unactivated win. If you have proof you sent them the gift then take it to support. "Misuse of Giveaway Feedback" is a permaban.

Hello Aoden

You should submit a ticket in "Request Received Feedback" category and provide a screenshot of your gift history like the one you posted here. Do not crop or edit it.
