Locked out of github due to 2 factor authentication

I have been locked out of my github account because of failed 2 factor authentication, i had it installed with Authy app of which i forgot the backup password, i have formatted my laptop so now i dont have any saved recovery codes, I have asked Authy for support but they were not able to help me and now my only option is to ask github support for help which i did 4 days ago but have not heard from them. As a result i am not being able to perform any of my task whether it is personal or professional. Has anyone got into this issue before and please suggest me how i can resolve this issue.
