Meta Facebook No Tech Support

My Facebook account was hacked and there is no way to rectify this. The hackers turned on two-factor authentication so I cannot log in to deactivate this. I even went to Meta office in Bryanston with absolutely no pleasure or assistance they seem to be used to annoyed customers. Managed to change my password but cannot get past 2FA authentication. Just need a Meta support person to deactivate 2FA authentication on my account to login again. 30 Year's memories lost otherwise. Please help 🙏
