Your best bet is to try and find a new bank. USAA's policy has been that if you have caused them to take a financial loss they will minimize their business dealing with you. With a bankruptcy, this will be an issue for 7 to 10 years.
I would recommend a local credit union, though it may not be easy with a bankruptcy on your record.
