8 days and counting delivery delay (Pathetic SLA)

I have never received such poor service in my life. The disappointment I am facing is out of his world. Placed an order on the 17-march till to date no one is giving me a proper answer as to when I will receive the order. I have been calling Makro and the courier guy and it has been a waste of time since they are not even acknowledging my calls nor the escalated calls. The courier guy route Manager (Mathew) promised to call me in the afternoon 25/03/2024 or morning of the 26/03/2024, I waited and still waiting on the for the call. I have to always pick up the phone and call to request feedback. Apparently, they are investigating their delivery error which is impacting me negatively. I am unable to explain what the hold is up on the delivery. The delivery worker came and checked with me if I have received my order and I politely confirmed that nothing was received. When I call the customer service department, they are quick to tell me the order was routed back to the Hub while it is clear the order never left their premises attachment to follow and
