Still waiting for my uograded headsets 20days later

I received a call for an upgrade on my headsets from Miriam lekoloane, a consultant @Vodacom. The upgrade was done on the 2nd December, Its the 22 Dec & I am still waiting for the phone.

First; I was told that there was not enough stock, then I was told Miriam listed the wrong address & contact details on my delivery details.

I have called all the contacts that I have for the service provider; I even went to a store in midrand but I have not received assistance.

I am beginning to wonder if I am the only person in the world right now going through this???
