AT&T started dinging me for late fees on my two accounts, which, of course, I ignored. I wasn’t about to accept that the post office was taking 7 or 8 days to send a check crosstown. AT&T kept insisting my bills were late so I finally asked them to send me a copy of the envelope with the postmark to prove my bills were, in fact, late. What do you know? Those late fees mysteriously disappeared from my statement!
