Certain members of Wells Fargo executive leadership team were likely aware that the company’s auto insurance branch was possibly overcharging customers for years, yet delayed on taking any action to rectify the situation. According to a report from Reuters, the problem was known about for almost four years before the bank decided to end the program.

These allegations have come to light after the details of a large class-action lawsuit were unsealed earlier this week. The documents allegedly showed that high-level Wells Fargo officers, “including then-General Counsel James Strother and chief auditor David Julian,” knew there was an issue with the billing system, according to Reuters.

“We have been reviewing customer accounts and developing a remediation plan — which we hope to finalize very soon,” said Wells Fargo spokeswoman Natalie Brown while speaking to Reuters. Brown also stated that the company would be reimbursing customers who were affected.

According to Reuters, Wells Fargo initially calculated the amount over-billed to be around $60 million; however, the company has exponentially increased that sum to more than $241 million.
