dishonest landlord in Dubai wants to keep my deposit

I rented a luxury apartment in Dubai about one year ago. Before the year was over, I decided not to renew the lease and move out. This was my first time living in Dubai so I am not familiar with the rules. I did not do a move in or move out report of the apartment. But I have taken pictures myself when I moved in and moved out. After moving out and returning the key, I was totally shocked by a report sent by the landlord accusing me of damage caused to the apartment which already existed before I moved it. Also, for damage that he totally made up. Basically he wanted to keep my entire deposit. Is there a way to dispute this? Did someone went through a similar experience?
