I just got this message as an SMS to my mobile broadband mobile number!
"Courtesy reminder: CommBank Credit Card ******** payment due on 07/07/17. Avoid a $20 late fee by paying on or before this date. Any questions, call 132221."
But I DON'T HAVE any credit cards, NOR any accounts with the C'wlth Bank.
