Aus Post is evidently doing some matching on its customer dataset and combining records that it perhaps ought not.
I’ve started receiving delivery status emails to a work mailbox when I order things to be sent to my house, because I use the same mobile number for both. I haven’t found a way to tell Aus Post to stop doing that.
Mum did a mail order with Minimax last week and got a delivery update saying that her parcel from [Minimax’s executive marketing manager’s name] was on board for delivery.
It’d be really nice if Aus Post worked only with the information I give it for each transaction. But this seems to be an unpopular opinion in corporate circles.
