NinjaOutreach... a scam?

I joined NinjaOutreach today just to try it out. It said the trial period is 14 days, good time enough to try it out. I made a few searches, but nothing relevant did actually come up. I did a search on my friend's name, I know he has a Youtube, Insta, Twitter and FB Account. So I was fairly sure that something on him would come up. But nothing. Minutes later the application hanged, A message "Your account was blocked due to unpaid subscription. To activate your account, please make it sure that you have a valid credit card to activate it." came up even though I still am in the first day of the 14 day trial period. Then I saw the application actually tried to charge my account twice, once on 299 USD and once on 1428 USD. Luckily enough, I didn't have funds enough on my card. But am afraid the application will make the withdraw as soon as there will be enough funds. Since the application tried to charge me at the very first day of the trial period, I suspect this application is a very well-done fraud. Moreover, there are no contact details to the company behind NinjaOutreach either whatsoever, there is a chat option, but it's not attended by anyone. I can't find any option how to terminate the account either. If there is someone out there who knows how to have the problem with NinjaOutreach fixed, or how to terminate the account with Ninja Outreach, I would be grateful to know.
