Complain to the Consumer Financial Protection Bureau. Your complaint will be posted in a public database.
Laura Murray with the consumer advocacy group U.S. PIRG said the vast majority do get a response.
"95 percent of complaints are closed and resolved through this process which is a great number. And that's within the 15 days that the CFPB requires," Murray said.
According to a PIRG analysis of the complaint database 28 percent of those who complained got some sort of tangible financial relief. Another 5 percent received non-monetary relief, such as adjusting terms of their account or correcting an error.
The nation's bankers say this shows how hard they work at making their customers happy.
By the way, the Consumer Financial Protection Bureau accepts complaints about a wide variety of financial service providers and products: mortgages, credit cards, student loans, auto loans, money transfer services, credit reports and debt collection.
