Wells Fargo has been accused by federal regulators of illegal activity on a stunning level. Authorities say employees at the bank secretly created millions of unauthorized bank and credit card accounts between 2011 and July 2015, allowing the bank to make more money in fees and meet internal sales targets.

Wells Fargo agreed to pay penalties of $185 million and fired 5,300 employees over the last few years related to this illegal activity. The news is rocking the industry and rippling across Wells Fargo's millions of customers nationwide.

Former employees tell CNNMoney that they felt incredible demands from managers to meet sales quotas. The same managers turned a blind eye when ethical and even legal lines were crossed.

"I had managers in my face yelling at me," Sabrina Bertrand, who worked as a licensed personal banker for Wells Fargo in Houston in 2013, told CNNMoney. "They wanted you to open up dual checking accounts for people that couldn't even manage their original checking account."
