Is this a scam?!

I signed up for a Free account, and prepaid for the 3 months. It was NOT supposed to automatically renew; the website states that the Premium account automatically renews, not the Free account. But they did automatically renew it, and there is no way to contact them to get a refund and make sure they don't charge me ever again. The contact button on the website doesn't work, there's no phone number listed on the website, and the phone number on my credit card statement linked to the charge is not working.

Cons
Wrongful charges on my credit card. No owners' names on the website; no mailing address; no customer support phone number; no contact email address; no way to reach them.
