Vodacom Service is Pathetic

On the 27th September, I ordered a Wifi Extender for my fibre router. Numerous email requests were sent to customer services to follow up and change my address as well, as every time I phoned they were telling me that the address on the system was where I stayed like 7 years ago and then I would phone again and my address from 2 years ago would come up. Someone needs to get their act together.

Anyway, the bigger problem is that I ordered the extender on 27 September which only came for delivery on the 6th October after they tried to deliver to one of my old addresses. the delivery consisted of a sim card and no extender, so I sent the parcel back with RAM. I got a call from Vodacom to say they need to do an internal investigation as to what happened to the extender. I have heard nothing since and wondering why the customer has to wait and be inconvenienced by something that happened in house. why does one have to complain before something gets done? I would like someone from management or someone who is competent to phone me and sort this out. This is absolute nonsense and lack of interest on Vodacom's part
