Hi. I have made a deposit for a house in Damac...

We would like to inform you that if you conclude the contract and paid a deposit, the basic principle is that you cannot recover the money  because it will be applied to the provisions of the deposit. But if the contract states otherwise, you may get the money back, so contact the lessor to reach an amicable solution.
Article (148) from the Civil Transactions Law:
1. In the absence of a clause to the contrary in the contract, the payment of earnest money is evidence that the contract has become final and may not be relinquished.
2. Where the parties agree that the earnest money paid is the sanction for withdrawal from the contract, either party may withdraw. If the payor of the earnest money is the one who withdraws he shall loose it and the person who has received the earnest money and withdraws from the contract shall repay double the amount received.
