No delivery of upgrade made three weeks ago.

My upgrade was finalised on the 1st of August. I have called MTN and DSV every single day after the estimated delivery time should've been the 8th of August. It is now the 17th of August and still no delivery arrangements have been made. DSV confirms that they have received the data file from MTN but no parcel as yet. The estimated delivery time has been overshot by more than a week now and other reviews have stated that they have waited more than a month for their delivery. MTN has said that the phone will be handed over to the couriers by either Monday or Tuesday when I call on Monday, 14 August, it hasn't happened. I called DSV Tuesday, 15 August to get confirmation on what MTN has said will happen and as expected, no parcel in DSV's possession. I'm getting frustrated with the whole arrangement procedure and I was well aware of the courier change. But i was under the impression that things will go smoother from here on out and it has been a constant struggle to just get reliable information from MTN. Weak service, everyone has a different assumption on what "will" happen. Tired of struggling. Why change the warehouse system and change couriers if it is just going to be more inefficient?
