USAA Savings Bank Account Or Service Complaint

USAA Savings Bank account or service department,

Checking account Problems caused by my funds being low Indiana

I have been banking with USAA for about - years. I have disputed the order of transactions several times but it continues to happen. For example, I will make a purchase and the funds will be available and the money taken out of my account. Then a few days or a - later the transaction will appear to have overdrawn causing a fee and the transactions will be out of order. It seems transactions are out of order for the convenience of the bank taking out bank overdraft fees. That causes of slippery slope of fees because the bank takes out money that is n't supposed to be taken out. That leaves the unknown of where the funds went that was taken out when the purchase was made. USAA is either stealing out of my account and charging fees or something.
