Wells Fargo Bank will lose customers in droves because of the scandal over fraudulently opened accounts and other issues, based on the results of an online survey cg42 conducted last week. More than 85 percent of the respondents — 1,500 primary customers of the top 10 U.S. retail banks, including 1,000 Wells Fargo customers — were aware of the scandal. Thirty percent of Wells Fargo’s customers were exploring banking alternatives, and 14 percent already had decided to switch banks because of it, the survey found.
