A former Wells Fargo & Co. employee in Los Angeles claimed that the bank still charged customers for missing deadlines for locking in loan interest rates, even when the bank was the cause of delay in mortgage paperwork.

According to a Nov. 23, 2016, letter written by Frank Chavez to the U.S. House Committee on Financial Services, the practice in the Los Angeles area alone would have netted the bank "millions of dollars." Chavez claims that he resigned in April 2016 and last worked at Wells Fargo Home Mortgage's Beverly Hills, Calif., office.
