What actions can I take against a bank for lack of customer service?
Figure out who regulates the bank. Complain to your state banking/consumer affairs department. Complain to your state Attorney General. The Feds regulate most banks too, there are several different agencies, and I believe the way they regulate banks has changed recently. Try contacting the US Comptroller of the Currency.
