Petrol Contamination

I'm writing this review over a heavy heart. I have a really bad experience with Mayville She'll garage in Pretoria. I layed my complaint with them regarding to what happened to my car after filling up their petrol, and it was confirmed from their cctv that indeed I was there. Very same day the petrol station owner called I told him my car broke down I later found out from the mechanic that the petrol was contaminated. He said it has never happened to him before with me it was the 1st time the I ddnt disagree with I said only telling him towards happened to me, I'm a shell regular customer I do not mix petrol sadly that is what happened to me after filling up at his station, that was on the 27th of March since he said he's escalating the matter to his bosses until this day, I also emailed She'll S A they are also quiet with my complaints, that show they don't care for customers only the customers money is important whereas I end up with a damage car
