Account recovery didn't work. I know my username, but not password. Email is same but phone num is not, and i no longer have access to number. How can I get into my acct?

I tried to submit a request to gain access to the account, but its asking for an old email account. The email isn't the problem though. I used my current email and I still have access to it. It's the phone number that I don't have access to, and when I click try something else and enter my personal info, it says it's not correct.
