Can you get your Roblox account back with no email or number?

I found my old account from 2016 and it does not have an email attached to it. Is there any way I can get it back? Any way at all? Anything special I can do?

The only way is if you bought Robux on it, with a bank statement.

Send Roblox your credit card number/ some of it if you bought Robux on the account.
