Account hacked need help ASAP

Hello,
My account has been hacked, I no longer have access to the back up e-mail that's on the account. I do have my cell number on it but when it texts me the 6 digit code 082251 (which is the only code they send me) to reset my password it says it's incorrect and I can't get into my account. I can however, if it helps to recover my account give you information about my bestie to prove that the account is REALLY mine.
