You can complain but the American Government is supporting that! MtGox is in hot water with the american government and they seized the bank accounts citing the financial regulation violations under unregistered financial exchange service. Paypal, Ebay credit card companies and many banks are operating under that guidelines.
It's matter of time, the major banks will figure out the oversea bank routing and account numbers for the Bitcoin Exchange/Market and deny more incoming and outgoing international wires. Until the government decide what to do with bitcoin, it could get harder to withdraw/exchange bitcoin into cash.
I could be wrong but this credit union openly stated they are supporting the Bitcoin or at least they don't interfere with Bitcoin related transactions.
