I closed my account with Wachovia/Wells Fargo on 9/2/09, receiving the total balance of my checking account from the teller. About a month later I received a bill from Wachovia for $60.
Apparently a charge came through a day after I closed my account (Shell Oil, $30) and because my account was closed with no balance they charged me a $30 NSF fee. I went into the bank to dispute the NSF fee, and they teller told me that due to them having to put me in Chexsystems I now owe a total of $101.70. My current bank is telling me that they are closing my account because of this.
