If you’ve ever felt scammed by a mortgage company, auto lender, credit reporting agency or other financial institution, you might have turned to the Consumer Financial Protection Bureau for help. In recent years, millions of Americans have filed complaints with the agency. Sometimes they did so after a long, unsuccessful back-and-forth with customer service representatives. In other cases, a friend, family member or advocate referred them.

The number of complaints — about payday loans, debt collection practices and more — has been growing steadily. The federal agency fielded 2.7 million of them last year, and half of those resulted in some kind of relief for consumers, according to agency data.
