Security deposit issues

The owner of my previous apartment has been ignoring my messages regarding the security deposit. Broker just told me na wala daw akong laban regarding that cos I didn’t finish the one year contract.

I moved in last December 2023 and moved out last November 2024. The owner even offered to deduct the rent for November using the security deposit. I paid for 1 month advance (covering December) and 2 months deposit.

Did I really finish the 1 year when I made an advanced payment and technically paid for November using the security deposit?
