I thank It's a scam, but not. I got a refund.
I asked to stop service immediately after I paid by credit card. I was sure, that I'll never see my money back. Unbelievable, but I got a full refund. It happened after 2 months of waiting but anyway, it was a good surprise. So in my case, it was not a scam. Just a very expensive service for a thing whose price is 7 CAD at the official site.
