The landlord renewed my tenancy contract without my knowledge or signature, what to do?

Assalamu Alaikum,

In 2019, I rented a studio in Al Ain for a short term with a fixed monthly rent payment. I was paying every month by 4 months.

In the middle of the 4th month, due to problems with the owner of the studio, I informed him that I was moving out of his studio. On December 20, 2019, I left his studio and handed over the keys to his office.

On 24 January 2020, the owner, without my knowledge, registered a rental contract with me for a year at Municipality. On this rental agreement, in place of my signature, there is a signature scan from my Emirates ID which was placed without my knowledge.

The landlord took me to Enforcement Court where I was ordered to pay 39,000 as rent. The Court of enforcement blocked my bank account.

What should I do, how can I legally claim my rights?

Can I appeal against the judge's decision?

How can I prove my innocence legally and try to extort money in my opinion?

What are the court fees and fees for the possible assistance of a lawyer through his services?
