They tried to use my CC to buy something on another website
When I signed up for this website and bought a course, I created a virtual card with my bank, bought the course, then deleted the virtual card. So basically, this CC was only ever used once, and then deleted. Today I got a notification from my bank that one of my deactivated virtual cards was used to try to make a purchase at a website where you can buy digital video games. I called my bank and the virtual card was the one I used for TutorialsDojo.
