Don't work for Superprof

If you want to do online tutoring, don't work for Superprof. They put me on their plan to charge $9/month to promote my ad without telling me and didn't display that information on my profile so I wouldn't have realized if I hadn't been monitoring my bank statements. It also seems shady because I had to dig into the ToS to find the email where I could cancel the subscription...I'm not sure if just deleting my account would have canceled the charges. And of course, I didn't get a single student from the site.
