Poor service

I have been waiting for a delivery since 23/01/2025 to no avail. The driver called me asking for directions which I gave him with all landmarks to note. Later that day I received an SMS informing me that the delivery has been rescheduled for 30/01/2025 with no explanation why. Come 30/01 no delivery and no communication until I called them and spoke to Rochelle. She told me that the driver tried to reach me and couldn't find me, I don't know why the delivery should be subject to the driver reaching me on the phone while my address is stated clearly on the package, meaning that if we can have network problems like we did yesterday I'll never receive the package. I told her I paid pro rata fee for the product which has now gone to waste. She told me that it's an unfortunate situation dsv can't do anything about. When I wanted to be transferred to complaints department she told me to complain to the service provider which is MTN. Or if I wanted to speak to someone senior she was going to check if he/she was still on the floor and request him/her to call me back. Till now I have not received a call from anyone. Their service is disgusting to say the least
