Rude customer consultant Thokozani Mbatha

I made a call to dstv because I got disconnected for a bill I was not aware of,I spoke to Thokozani Mbatha with call *** who was so rude and unprofessional telling me about something that happened in July when we are in October, me trying to understand the query she then rudely shouted/snapped at me,while explaining my frustration she then put my call on mute and didn't even bother to talk back at me that I ended up talking to myself with my airtimes,I'm sure she is used to call avoidance that she always gets away with it but people like her should not assist customers because she clearly doesn't know her job description
