The feds have created a new place for homeowners with mortgage complaints to contact and (hopefully) get them resolved. This includes escrow disputes, mortgage modification issues, or mortgage fraud. you can go online to www.consumerfinance.gov, or call toll-free 1-855-411-2372. It was created through the Dodd-Frank banking law that passed in 2010. What can they do for you? They are supposed to mediate complaints, and if a complaint isn't within their sphere of power, they will refer you to an appropriate agency.
They also field credit card disputes. If you run into your very own "Peggy," or have other credit card problems that can't be resolved you can file a complaint.
It's got other good stuff: a page on student debt--with information to know BEFORE you get into student debt, and an online "assistant" to walk you through your options now that you have a ton of student debt.
