Late payment fee was charged even though I paid bill before due date? is it justified?

Whether it's on the weekend or not, paying by the close of business on the due date isn't supposed to cause a late fee or interest, even if the final posting date is a day or two later.

@HeavenOhio yeah, I'm sure that's the party line, but I wouldn't trust that logic one bit. Payments should always be made far enough in advance of the due date that this issue is diminished into non-existence.
