Read the Guidelines carefully.- https://www.steamgifts.com/about/guidelines
Beta keys which do not provide unrestricted access to the full game in the future, guest passes, demos, and coupons cannot be given away.
Giveaways need to accurately reflect the game being given away. If the game is not available in the giveaway list, please contact support to have the game added, instead of posting the giveaway under an incorrect name.

Make a request to support to remove your false giveaway or replace the key corresponding to the name of the game
