Bogus Late Fee
Wells Fargo. I had closed a savings account years ago. Somehow, Wells Fargo claimed that I had incurred a withdraw from the savings account. It turned out to have been an error on their part. However, they tacked on an “overdraft fee” of $15. I noticed it in my checking account.
When I inquired, they said that it was because there were no funds in the savings account. But the account had been closed for years! I spent an entire week calling and e-mailing different departments (referred to me by different reps). I felt that I was at the mercy of whatever erroneous charge they wanted to throw at me. Ultimately, I believe nothing would have been corrected had I not e-mailed every Wells Fargo director that I could find on the internet.
Eventually I was advised that they had recalled the bogus late fee, but made sure to get it in writing. I stopped banking with them at that time.
