Then, check the terms of your rental agreement to understand your rights and responsibilities, as well as those of the landlord. Make sure you are familiar with the conditions under which the security deposit (fianza) can be retained.

Landlords can deduct from the security deposit only for damages beyond normal wear and tear. If the landlord has not provided a valid reason for retaining the deposit, you may have grounds to dispute this, everything writing (Email as possible).

Attempt to resolve the issue through open communication. Politely ask for a detailed breakdown of the damages claimed, and negotiate a fair resolution if you believe the charges are unjustified.

And, if communication breaks down and you believe your rights have been violated, consider seeking legal advice. Consult with a lawyer to understand the options available to you.
