Bestdrive rusteburger

This branch and all it's workers and management are ******, they allow the mechanics there take money aside from customers, once you report that matter to the management, they then tell you that they will open a case on you for bribary. As I heard am not the 1st one this happens to, I regret taking my car to bestdrive in rusteburger, they ******, the time i reported the matter to manage ment thry told me they will guve me fitback after 2days l, i wated 3 weeks for a feedback. I then took myself there to find out what's going in the manger tells me he will lay a bribary case on me, and yet I told them, Thier worker demanded money for me to replace the parts I took in my car for. I just need to know where do people like this be reported
