4th Complaint - Still NO response since Jan 2016!!

I have still not been contacted regarding my query (5 weeks later) and now vodacom has the audacity to block my line. I have been harassed daily by an IVR collections call with a \beep\" in the beginning of the call loud enough to physically damage your ear and I am certain will be unsafe in terms of the OHS act. I was sent an SMS to prevent me from going to ICASA after my previous complaint, however still NO call! Will someone senior at Vodacom please call me today still! I have been on the pone with Vodacom now for 35 minutes - Been transferred 6 times between departments and spoke to a TL (Tabelo Mlilo) who refused to take accountability for my query...i had to argue with him for 10 minutes just to get his surname. Is this Vodacom's perception of good customer service?! Vodacom is pathetic!! Please cancel this contract, I'd rather get a phone via ****** Cell C than struggle with this disgusting service!! #VodacomMustFall #BrandFail"
