NON ASSISTANCE OR JOY WITH VODACOM BILLING DEPT

I have been trying to engage with Vodacom billing for two weeks. I have a query but can't even get to speak to someone, anyone in the billing department. I have been into theVodacom store, but no luck. They also told me to contact the billing dept. It us a really poor show. I have called left mssg, call centre gas called Mr back but just put me into the same queue! ITS JUST TOO FRUSTRATING FOR WORDS
