KarateAcademyOnline Sensei Mark Taking money out of my checking account, and not providing the karate classes. Internet

I paid $7 for an intoductory karate class. I was able to complete only a couple steps within the site, but the remainder of the introduction did not function. I called the phone number, but it was not in service. I emailed, but received no response back. I tried to log back in, but the site will not recognize my email address now. I hit the Support button on the log in page, but it is not functional. Since then, the company has taken out $47 from my bank account twice. I'm still unable to reach them by phone/email.
