I have a complaint on the shell gas station located on the corner of van horne and decarie in montreal. I went to pump some gas and when I went inside to pay, the guy in the cash tried to charge someone else bill on my card. When I realized and told him, he got really aggressive and talked very irrespectfully. When I decided to pay at the pump, he blocked the service so that i couldn't even get gas. His name was Farid. I believe I was totally discriminated based on my skin color. When I went back inside to ask why the keypad wasn't working, they just laughed at me. I think this is the worst customer service I have faced in my entire life. I will never go to another shell gas station ever in my life.
