Financially strapped, Jose Aguilar said it felt as though he'd let his family down in 2015 when Wells Fargo foreclosed on his mortgage , but his disappointment redoubled earlier this year when the bank sent him a letter that said a system glitch that he says caused him to lose his home of four years. Aguilar is one of an estimated 545 customers who lost their homes when the bank incorrectly denied 870 loan modification requests due to calculation errors.
