I was took for granted

I got the worst service ever at FasFit Rustenburg March I went for my brake Discs ,front brake pads and front bearings and again July I went for the same thing so now my bearing are making some noice again I went back they checked it and confirm its the bearings again I was told that the supply is out of stock and what I can do is order other bearings which am not sure how safe they are and they will take the one I have for a test I think this service need really investigation because they putting motor riders in danger because we can not been buying part like this and get this stupit explanation's like this I believe this is not complying to customer protection act is against it totally
