Useless as hell

I am fighting with Vodacom almost every 3-4 months because my account is permanently a mess up. I have insurance on my phone that I am not aware of so I am being billed for it. I keep adding this to hello peter and nothing gets done I am gatvol of Vodacom. I want them to cancel both my contracts. They r frustrating me one way. Every single month need to put them on hello peter or everyday or week they r added to hello peter but nothing gets done. They r useless but when they want money they quick to block your phone but when comes to sorting out clients they make clients run behind them.
