Owner Threatens to hit customer for not wanting to listen to his side of the story

I will not recommend anyone to bring their bike or car to them for a service. They don't know how to work with customers and when you try and talk to the owner about the extra problems they have caused (with my bike), he threatens to hit you. They don't take responsibility for their action's and they don't have pride in the work they do. They just want your money. I took my bike in and it came out worse with a flat battery and the one brake that doesn't work. Please be very careful with this auto shop. That owner must NOT work with customers or even own a business. Please becareful when it comes to PB Auto in Boksburg
