Boksburg branch is *****ulent

I had my vehicle crashed into another vehicle by the mechanic. I was promised it would be fixed with there insurance and panelbeater. When i got the car back, the mechanic had tried to fix it himself by as they made him pay for it. So things were just melted instead of replaced, cracks in bumper just painted over, bonnet still bent. On top of this, I spent over R40000 getting my car fixed, everything they said they fixed I have had to redo at another mechanic including replace my engine. I have tried to get hold of Bosch head office with no luck. Avoid Bosch at all costs.
