Transfer I didn’t authorize

I lost my apartment in November, and at the time my account was paid in full. I was given the option to put a hold on my account until I had found a new place. Unfortunately it is March and I have not been able to find housing for myself. Recently someone must have moved into my old apartment, and I am now being charged over $200 dollars for transfers and fees that are not mine. They are from the new apartment tenants. I have made 2 complaints about this and I am

still being held responsible for these fees thst I never authorized or agreed to.
