I have had nothing but trouble from Wells Fargo as well. It's scary that they make such huge errors with accounts. This is my financial well-being here!
A couple of years ago, I went to close one of my accounts I had with them, but keep the other one open. What did they do? They closed ALL of my accounts. It was a pain in the butt to clean that mess up.

Another big mistake on their part was a line of credit account. After paying it off, apparently their computers weren't tracking and I just found out last month that I've been accruing delinquencies on that account. WTF? I paid that sucker off and had no idea that all of this was going on until I tried to apply for a credit card and my application was turned down. I was shocked, considering I have exceptionally good credit. I pay all of my bills on time, every time. I called right away to find out why my application was turned down, and came to find out about the line of credit account, which had been paid off in full months ago. Even when I logged into my online statements there was a balance of $0.00 because I paid it off. It scares me to think that there is such a disconnect causing issues like these.

A friend of mine told me how Wells Fargo had associated someone else to her social security number, and that person then spent $17000 through her account! How does that happen? Not to mention it was a mexican man associated to a very clearly amerian woman's account! How can something major like that even happen?? Scary...
