I received a letter from USAA indicating that my credit cards are being closed due to 'unacceptable behavior or activity '. I called USAA and they will not explain the behavior or activity that was 'unacceptable ' to them, nor will they reconsider opening the accounts. This is significantly detrimental to my credit history as this was XXXX of the XXXX credit cards I opened over 10 years ago.
