I signed a tenancy contract and the landlord failed to finish renovation on time. What can I do?

Good day.

I have signed a tenancy agreement via agent for the townhouse to rent in Abu Dhabi on 24 June with a start date of rental on 1st July.

Repairs/Repaint works from the previous tenant were yet to be completed by the landlord and are confirmed by the agent that will be finished in a few days' time.

I have paid a deposit, agency fees, and 1st payment for 6 months. I received keys on 2nd July and found the rented unit without any significant repairs/repaints done.

I returned the keys of the property on the same day to the agent and asked to contact the owner to correct all deficiencies prior to moving.

I'm concerned that nothing will be done to resolve this issue promptly (I understand that the key is still not collected from the agent by the landlord so works have not been started yet).

What can I do in this situation?

What is the process if I want to terminate the contract and receive my money back for the deposit and 1 payment (as well as agency payments)?

Thank you

RG
