On a per capita basis, no consumers complain more about credit cards than those in the District of Columbia reports the CFPB. Or course, the District just happens to be the home of the CFPB and a large number of its staff. And those same D.C. residents are apparently number two on mortgage complaints, followed by surprising number one, New Hampshire. Adding to the faux conspiracy: nearby Maryland is number two in mortgage complaints, and number three for credit cards. Hmmm.
