Michaela Christian lost a long battle with Wells Fargo in 2013 to save her Las Vegas home, a defeat she says changed the course of her life. When the bank refused to modify her mortgage, Christian moved in with a friend and scrambled to rebuild her life. Five years later, Wells Fargo admits it made a mistake. It is a mistake the giant bank admits it made nearly 900 times over several years, pushing hundreds of distressed homeowners into foreclosure. Christian said when she learned of Wells Fargo's error, I was sick to my stomach. They destroyed me and destroyed my everything." Wells Fargo says an internal review found that the bank denied help to hundreds of homeowners after fees charged by foreclosure attorneys were improperly used when the bank determined whom to offer mortgage help. The computer error began in 2010 and was not corrected until last April, the bank said. Wells Fargo's admission is part of a cascade of lapses that increased scrutiny of the San Francisco-based bank. Over the past two years, the bank paid more than $1 billion in fines after admitting it opened millions of bogus accounts customers didn't want and then found itself in more trouble after improperly repossessing thousands of cars. Critics have also jumped on Wells Fargo's decision to cut 26,000 jobs while it reaps the benefits of a corporate tax cut that is expected to boost its profits $3.7 billion this year.
