Admin removed me from app lab in attempt to hijack account t

Hi, I don’t know if I’m in the right area but I’m in a pickle, I had a partner helping me develop apps on app lab who I gave admin privileges to. He has removed me from the account, but in my app lab account I can still see the studio. My name is on the account with Meta, my drivers license is what was used to create the account. I’m looking for help to get this back there is no way to contact meta directly to talk to them about the situation if anyone has any thing or any idea of what can be done please let me know.
