Terrible service Mazda Boksburg

Took my car in for service at Mazda Boksburg,the service response when collecting the car after service...Service consultants were unhelpful and very unfriendly bordering on racist as the person before us,of a lighter hue was assisted with speed and ease.They then allegedly put resin on the windscreen to stop a chip that wasn't running anyway but it seems like they didn't do anything. I am really disappointed in the service.
