Look here if you have bought revoked gifts:

1. Accounts listed above includes the owner of this account and one of his alt. trading account.
2. If you have bought revoked gifts, contacting the seller via these accounts for resolution is more effective than contacting Dispenser.tf.
3. If needed, these are the accounts to be reported to Steam support.

''Steam restricts all gifts from being used in a Steam trade for 30 days after their original purchase date. However, you can still use the 'Send A Gift' feature to send this game to a friend at any time''
