Two Step Authetification

So recently I bought account I changed number everything but forgot to change two step authentication number. Now I can’t no longer access that account because some Indian number asks for verification. And previous owner resold account to me so he doesn’t know that number.
Can I bypass anyhow that two step authentication?

I guess the reseller does not have backup codes?

no he doesn’t:(

sorry to say that but you should looking to buy a new account
