I rented a car and asked for 1000qar deposit. They said they will give it 1 week after a gave back the car. Now, half month passed already and I don't have any call back from them to get the check. They always tell that it is not yet available to the accountant, but don't say the exact date it is ready. Is this normal? It's my first time to rent. Do i need to file a complaint against them now? How?

Thank you.
