Reason 1: The automated telephone messaging service (TM3) calls the customer to deliver the hold or overdue notice. If it is unsuccessful after 3 tries (no answer, line disconnected, fax machine, not ringing, etc.), that notice will be printed and mailed via USPS the next business day. Look at the notification block on the customer's account to see whether it was complete or incomplete.
What can you do? Verify the customer's phone number. Do they have an answering machine? There are a few types of answering machines that do not work with TM3. TM3 only recognizes these area codes. Do they have an alternate number? Would they like to try email notification instead?
Complete - the notice was delivered by phone
