Facebook Two-Factor Authentication Code Issue Needs Urgent Fix

I've been having trouble logging into my Facebook account for the past few months, and it's becoming increasingly frustrating. The two-factor authentication code is not being transmitted, and the "Forgot Password" option is also not working. The problem has not been resolved, and I am still unable to obtain any codes despite switching internet providers, which was supposed to occur within 75 hours. I am unable to create a new account as a result of this situation because some apps are linked to the one I already have. I'm at a loss for what to do and extremely frustrated, and I need Facebook to fix the two-factor authentication code problem as soon as possible. Your assistance would be greatly appreciated if it could be provided as soon as possible. Thank you very much.
