STILL NO SERVICE FROM VODACOM!!

This is the third report that I am writing about the poor service that I keep receiving from Vodacom. After the last report Vodacom rep**** to me privately requesting that I call their number *** to sort out the issue. I did this and spoke to a Phina Mase who was not helpful at all and basically did not have a clue on how to handle the matter. She assured me that someone senior would contact me and it has been almost a week and I have not been contacted by anyone from Vodacom. Phina also refused to give me a reference number and assured me that it would be sms'd to me. Needless this to say this also has not happened. How does one receive some kind of service from these people??
