Disappointed/ angry and need help

I am very disappointed and angry in the way my account was handle, I have a car insurance with Dot sure to my suprise extra money was debited in December and January claiming that I requested additional policy for scratch and dent which I did not . I called and talked the Edwin Cloete who promise to cancel and reverse my money to date he has not even calling nothing. I have to call and talk to different people who promise they will tell him to call, still waiting. R632 is lot of money for just going down on drain for nothing I don't want that scratch and dent thing did not ask for it. Snowy Mosia
