Locked Account And Lacking Information To Unlock It

Hello,I recently experienced trouble accessing my account to make a car payment last month due to inputting an incorrect password therefore my account got locked. I was able to use the One Time entry though, as well as changing my password for future reference. However, I needed to change some information on my account a day later so when I attempted to log in, It brought me to my security questions. I am positive that I answered them correctly, however I've been locked out of my account again.. I have tried calling BB&T on the phone but cannot get to anyone for help. The only information I have on record is my Loan Account Number with BB&T. I have never received a BB&T Debit or Credit Card # or PIN # to my knowledge.. just a Loan Account Number and basic log-in information is all I have. How can I unlock my account??
