Autozone Klipfontein got Side Hustles with very bad attitude

I went to purchase a car part on these motor spares (Autozone klipfontein) , the service of Dumsani Maseko is very bad. I waited for days for my part to be delivered which I did understood. How ever upon he delivered a incorrect part, I spoke to his manager and the gentleman tried to resolve our disputes my refund in a professional way. It has come to my conclusion that Mr Maseko might be doing side hustle at Autozone because he was telling me that there guys that he know that can give the cylinder cheaper. Upon he kept on stigmaring me that I must know the refund process because of where I am working.
