Revision after facial surgery gave me nerve damage

Hello there, 5 years ago Dr Simon Rosenbaum gave me a lower facelift that gave me nerve damage. A year later he tried to fix it and made it worse. He refunded me and I signed papers saying I wouldn't sue and he would help me. I've been having botox and fillers for 4 years. Simon 6 months ago lost interest and I really need help. Can my face be fixed?
