COURIERIT Delivery INCOMPETENCE

I placed an order with TELKOM, which is supposed to be delivered by the Courier IT team. The first delivery effort was unsuccessful owing to my delivery address, which they claim is UNKNOWN. I called their CALL CENTER number to find out what was going on, and they informed me that I needed to go back to TELKOM so that they could alter my address because they weren't permitted to because technically I was Telkom's client, which I did. Fast forward to without any news on the progress of my delivery, I got the same SMS again stating that my delivery is UNKNOWN, the courier it delivery driver never attempts to call my numbers, to arrange for directions for an Estimate Time of Arrival. I HAVE TRIED TO CALL THEIR NUMBER AGAIN AND THEY STILL TELL ME THE SAME STORY.

COURIER IT REALLY NEEDS TO DO BETTER WHEN IT COMES TO CUSTOMER SERVICE, THEIS TYPE OF SERVICE IS INTOLERABLE!!!!!!
