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.

I have games in Indonesia pricing. Check the yellow info of the gifts to see if it's ROW or SEA Region locked.
How to use bot trading (Sign in through Steam):
1. Choose the game you want.
2. Choose the type of keys that you have.
3. Click 'Purchase' on right bottom corner.
4. Accept the trade offer that bot will send you.
5. (For Untradeable) you will need to give the keys 1st, the bot will automatically send you the gift after that.
If you like the bot, pls rate 5 stars.
