What is a UAF paid item penalty mean I bank with suntrust and i found this on my statement.?
I just found the same thing on my suntrust bank statement, but it's NSF paid items penalty $35 ???
l found a similar charge, stating NSF Paid ltems Penalty-$105. l found this was a charge for overdrawing. . . Very unnecessary charge, but still.
