Letter snafu marks Wells Fargo's effort to aid customers forced to buy unneeded insurance

Wells Fargo also offered refunds to customers last year after acknowledging that its mortgage bankers unfairly charged them fees to lock in interest rates on mortgages. The bank, the country’s largest mortgage lender, already has begun refunding some customers who have complained about the fees but is still working out a broader outreach plan for all of the 110,000 affected clients.
