unhappy customer

About 2 weeks I ordered upgraded do an S5 gold. The girl that helped me said the phone would be in, in a few days time. 2 weeks later I am still waiting for my phone. I called on Monday, she then said stock is arriving on the Wednesday and she'd call me. Guess what I had to call them using my airtime once again to follow up. Only to hear that the gold has been discontinued as well as the blue and the white. So no one could tell , me this earlier and then she says the black might only arrive next week Friday. .. 3 weeks for a phone? Common vodacom u r service suck. A customer whose upgrading should be kept updated on the process and a follow up to the supplier should be done- pathetic. I feel like cancelling
