Bank of America Corp. accounted for the largest share of consumer complaints lodged with the Consumer Financial Protection Bureau over the past 16 months, the Wall Street Journal reported today. The CFPB's expanded database unveiled yesterday shows the majority, or nearly 55 percent, of the more than 90,000 complaints filed with the agency relate to mortgages, the latest indication of the problems banks face in response to a surge in foreclosures. Credit cards ranked as the second-biggest source of complaints, accounting for almost 22 percent of the total. Complaints about Bank of America outpaced Wells Fargo & Co. and JPMorgan Chase & Co., whose consumer operations are comparable in size. The Charlotte, N.C.-based bank accounted for about 23 percent of the total complaints related to mortgages, credit cards, student loans and other consumer products filed with the agency since December 2011.
