POOR SERVICE FROM DSV/ MTN

I was waiting for a delivery from MTN, which DSV would do. When the driver from DSV arrived with my parcel he asked for my ID and proof of residence which I gave to him and I was authenticated. Then he tried to do a biometric scan. He told me his machine was not working and he could not deliver my parcel as he would lose his job. It was not my fault that the device was not working but he left and said he would be back the next day. However, when I called the next day they did not have a delivery for me until another day. I find this unacceptable as I had clearly had the necessary documents.
