NYC Housing Authority [NYCHA]

My name is Samuel Fraticelli [protected]) 9 months ago my mother Elba Pacheco resident at 185-Nevins St #14-J passed away. Two weeks later I had a walk thru completed and returned house keys to Manager Ms. Reid. I have made four complaints about Ms. Reid because I still don't have my mother's rent deposit. What can I do, who can I complain to?
Help

On March 23rd of 2019, my mother Elba Pacheco who resided at 185 Nevins St apt 14J passed away of severe medical health issues. On 4/42019 I completed a walk thru of my mother apartment with an Assistant Manager of 185-Nevins St. After the walk thru I provided management with all available keys and submitted written documentation that I Samuel Fraticelli([protected])am the only son of Elba Pacheco and was the only one with keys. I have been to Management Office for the past 6 months requesting my mother's rent deposit and I have yet to receive it. I've been to NYC Housing Office in Downtown NYC and requested my mother's deposit. Only to be told that Manager Reid has not submitted any documentation. I have Ms. Reid is expressing her prejudice to me because I belong to a Motorcycle Association whom she does not like. I am fully aware that my mother's apartment has already been re-rented and I can't understand why the deposit has not been executed. I would like to request a hearing with Housing so that this matter can be resolved.
Sincerely
