3 Cell C upgrade attempts, 6 months later and still no phone

I have been trying to get an upgrade from Nov 25 , the first time I called to make an upgrade nothing was done about it. I called again in Jan 26 and started the process all over again and everything was done until I called to find out where my delivery was. At the end of the second upgrade attempt all I needed to do was wait for the delivery team to deliver my new phone. However when I called to follow up I was told today that the upgrade was cancelled no notice , nothing so now I have to start the THIRD upgrade attempt , this is really frustrating and poor service.
