Worst customer service experience

I've received a message on the 10th November for a parcel collection, and I'm shocked that to date, the parcel is still not collected. I've called the contact center on the 11th November and I was promised that collection will be done before 15:30 the same day. I called again on Saturday and I was promised that my query has been escalated and collection will be done on Monday. I called again today and I was told that my query has been escalated to the Jhb office and I will receive a call shortly. It's now 14:15, I still haven't received any feedback and the parcel is still here. I'm extremely disappointed and frustrated with the level of your service. You are the worst of the worst
