RECEIVED A LATE FEE ON MY INVOICE.

BECAUSE I HAD PAID "IN ADVANCE" OF RECEIVING THE PAPER INVOICE.

I HAD SUBMITTED A PAYMENT A WEEK BEFORE THE INVOICE HAD BEEN MAILED BY US AIR (AND PRESUMABLY BEFORE THE STATEMENT CLOSING DATE)

THEY WOULD NOT COUNT RECOGNIZE THIS AS AN ON-TIME PAYMENT BECAUSE IT WAS NOT RECEIVED EXACTLY BETWEEN THE STATEMENT "CLOSING DATE" AND THE STATEMENT "DUE DATE" - IT WAS ACTUALLY RECEIVED BEFORE BEFORE BEFORE THE CLOSING DATE (I HAD GONE TO THEIR WEBSITE TO CALCULATE HOW MUCH 1/3 OF THE STATEMENT WOULD BE -

THEY DID NOT UNDERSTAND AND INSISTED THAT I DID NOT MAKE A PAYMENT PRIOR TO THE STATEMENT DUE DATE.
