Tortoise slow courier service

It took from the first notification that my parcel was on its way to me from Buffalo on 13 December, to 3 January for it to be delivered. Unacceptable. Both the sender of the parcel and I tried to contact Buffalo but there was no response to emails and phoning resulted in the sender being placed number 300 in the queue - no one can hold on for that length of time. The final leg of the delivery journey was handed over to Fastway couriers. They are equally bad. It took over a week of notifications that the parcel was on board the final delivery vehicle and would be with me that day, for the parcel to finally be delivered, and this was in the small town of Pietermaritzburg. Both the sender and I tried to contact the company. There was no response from the local depot - neither to emails nor phone calls. On phoning the next depot away, Durban, I was brusquely told that I must register complaints or issues on their website and the phone was rudely cut off without even a farewell let alone listening to what I had to say. The website form was very difficult to navigate and when I finally mastered this, there was an unconvincing automated response which did not evoke confidence.
