Epic billling fail!

Dear sir<br> <br> I upgraded my 2 year contract last month and managed to reduce my monthly bill. Or so I thought. My first bill was at the new lower rate, but the next bill was back to my old (higher) amount. I called customer care who said I should be getting free, some of the things I was paying for and there was some issue of being charged for screen insurance which I didn't ask for? This was over a week ago and I have not received a s**** of feedback since...despite the customer care guy (who didn't give me a name or contact number) telling me he would call me back the next day!<br> <br> I guess i have no choice but to move to Mtn or Cellc? Vodacom customer care...a contradiction in terms :-(<br> <br> Regards<br> <br> Michael<br> <br>
