Garbage customer service centre

I am a brand manager student, studied it for 3 years at this point. And Vodacom has single handily ruined their brand reputation with me, I got a new account under my name and signed up for a good data package. And let me tell you, the sign up process was smooth!!! But after that, everything went downhill, I was constantly being billed the incorrect amount and after emailing and calling the problem seemed to get solved, but no 6 months later I am still facing the same issues as day 1.

They need to fix there customer service team, and actually fix customers issues!!
