Office of the Comptroller of the Currency
If you have a problem with Wells Fargo or any other national bank, you can make a formal complaint here. The bank will listen to you after you do this. They do not like to get these kinds of complaints. As a matter of fact if they get too many they could be in for big problems. I would suggest that you make a formal complaint to the Comptroller of the Currency.
