USAA Savings Bank Account Or Service Complaint

USAA Savings Bank account or service department,

Checking account Account opening, closing, or management

i called in to open a checking account with USAA back in late 2015, whne i was told that i already had a account with them. I told the Rep that i have never opened a previous account with them, so she ask me some personal info to verify what she had on file. the info did not match so she changed it to my current info so who ever was using the account could not continue to use it. i later contacted the fraud department about the discovery conducted a investigation. they gave me a call about a week later stating that i a am still responsible for the negative balance on the account since the infomation matches. i told them that i just updated my info with a customer service rep eariler. i have been trying to resolve this for quite some time but USAA is cooperating at all.
