Ha! Ha! You make a mistake which cost you a peanut amount of QR 300 and you call that a GIFT.
Go ahead and do everything you can do take back that GIFT. You can rub your nose in the sand for that.
It is very difficult to get back money from any government in any country let alone Qatar over such mistakes. If you still continue to feel the pangs of pain from the loss, consult a psychiatrist, take some pills for comfort and good sleep.
