New Property Management Doesn't Have Record of My Deposit

[Hai-Dang Tran]

I live in Dallas, Texas and recently just moved out of my apartment. The property had several changes in property management. I used to live in a one bed room apartment with $750 security deposit then transfer to a 2 bedroom apartment, therefore my security deposit should transfer to the new unit with an additional $250 in order to add up to the first month rent which is $1000. The current PM claim that they only have the record of my new unit with the $250 deposit (where I received non back after all the fees) and they don't have access to any of the record of my previous unit. So now I'm losing $750 which doesn't make any sense at all. I don't have my lease contract since I have live there for over 6 years. What is my option in this case? Thank you.
