1. no proper receipt for the cash I paid. 2. I asked chang two used tires for $300. later I figure out one of them completely worn can not possibly pass a safety test. I went back tried to argue with, he said that worn tire is mine he changed only one tire. wich is impossible. because when I went there the tire he denied changing is spare tire, it's in my trunk now! 3. Even he didn't lie, $300 for one good used tire?!!! Surjit Auto Service at 711 Lakeshore E, Mississauga. If you don't trust me before go there check google review from others.
