I'm a Well's Fargo "customer" (more like a hostage) because they bought my mortgage from the local lender I originally went through. I have no legal way to stop being a Well's Fargo "customer" that does not result in direct and long-term financial penalties. Considering that they hold one of the largest mortgage portfolios in the US, I'd guess that many other "customers" of Well's Fargo are in the same boat.

I hate both Bank of America and Well's Fargo with a passion and the outcome of 2008 didn't dissuade my disgust at them. Unfortunately both hold loans from me that I did not initially originate with them.
