Worst service ever

Peugeot in Somerset West owner by Rola group. was the place were I got the Worst Service ever. That's the first garage in my life chasing a customer away. Their excuse is that they don't have the staff / autoelectrician with the proper knowlege to diagnose my Peugot. If that is the case I'm absolutely worried that they capable to maintain any other car they are selling. If possible my rating would be zero stars. Would suggest any potential buyer not to buy any car at this place in fact that they are absolutely non professionals in maintaining the car afterwards.
