Poor customer service!!!

On the 25th of August, the delivery of my parcel was supposed to happen, this was not the case until I decided to contact their call center to find out what had happened as the waybill number was no longer updating on their website. The agent over the phone also seemed puzzled and did not know what was going and put me on hold for more than five minutes to find out what happened. Only to come back to tell me that the car had been highjacked that day and that someone will call me regarding the matter. It has now been over two weeks with no one calling to let me know the way forward regarding the process. This was very bad customer service on their side as there was no communication from their side. The agent told me that the operations manager would be getting in contact with me to explain what had happened however nothing has been done since then, I was given the names of Ole Mathebula and Sello who were to contact me no communication has been made from their part.
