Few consumers who complained to the Consumer Financial Protection Bureau last year were able to obtain money for their efforts.

Just over 7,000, or 4.3 percent, of all closed cases resulted in monetary compensation from the target of the consumer complaint—usually a lender, according to a CFPB report.

Of mortgage complaints, the biggest source of CFPB-reported trouble, only 2 percent led to monetary compensation. The same figure held true for complaints against debt collectors and half that ratio for credit reporting companies.

Consumers with complaints against credit card companies fared considerably better with a 22-percent money award rate. Consumer and student loan complaints resulted in an 8-percent compensation rate.

The figures were made available by the agency today in a report on its second full year of collecting consumer grievances.

CFPB complaint center volume rose 80 percent to 163,700 in 2013 from 91,000 in 2012

The agency’s Consumer Complaint Database launched June 19, 2012, with credit card grievances and has been expanded to include mortgage loan, money transfer credit reporting, debt collection, bank account and student loan complaints.

Mortgage loans are the biggest source of consumer ire, accounting for 37 percent of complaints; debt collection is second at 19 percent

Three-quarters of the mortgage loan complaints related to payment problems.

About a third of the debt collection complaints involved consumers who alleged they were being dunned for money they did not owe.

Close to 18,000 complaints were about incorrect information on credit reports.
