I should have check this site and read the other comments. I too was scammed by Cancel Hero. It happened when canceling Blue Apron, an online food delivery business. When canceling, Cancel Hero popped up and I assumed it was part of Blue Apron. The transaction cost $37. Later I found out that Blue Apron does not charge for cancelations. Now I'm fighting the charge with my credit card company. I'm having a difficult time trying to convince them that Cancel Hero is a fraudulent business. I hope my experience will prevent someone else from being victimized.
