VERY DISAPPOINTING - VODACOM

I have upgraded my contract beginning of 1st of March. I am still waiting for my phone even today and when I call every time I get told that they are still waiting for stock to arrive. Last week I called and was told stock is arriving on Friday 18th March. Today I call again, they are telling me my phone is out stock and another stock is arriving on the 1st April. Like how long must I wait for my phone really guys?? This is absolutely ridiculous and annoying. I am disappointed on Vodacom cause this mobile provider I always trusted all the years I have been with them but I am getting ridiculous service. It's so frustrating. How can it be so hard for the stock to arrive and one get their phone?????
