Facebook authentication code

Hello,

Hello,
First, i couldnt login into my old account because the authentication code was not send to my phone. I cant contact facebook support to solve this problem, So i created another fb account under my phone numbers (last account was registered with email, but two authentication factor is under my phone number) .. Then I got email from facebook saying that they removed my fone numbers from my old fb because the fone number was belong to another person (ofcouse that person was me).. so now they removed the phone numbers, if I login my old account, the authentication code will send to whom?
Please help, i need to get my old account back...
