A Twin Cities woman is suing TCF Financial Corporation claiming the bank manipulated her debit card transactions to generate more overdraft fees. Kimberly Pellett of Savage says TCF grouped her transactions together, then processed them from the largest dollar amount to the smallest, which depleted her checking account faster. Pellett says she was charged $476 in overdraft fees in just six days. The suit seeks to stop TCF from reordering transactions and reimburse customers for the fees it collected through the practice.
