U.S. Bank Branch

The bank has been charging me a fee on checking for 4-years. I recently discovered that the fee shouldn't be charged to my account but they won't refund more than 6-months of deductions because: "you had access to online checking." Yes! I did! I also saw the fees deducted. I also asked about them 4-years ago and was told that all customers with a balance below 25,000 would have that fee -- a lie.
