Wow. It is really a scam (after comments was read). I returned my money immediately after I chargebacked it with my bank. But I have a digital card so I opened another one, transfered money there and closed the old one because these bandits can charge again.
My feedback from appstore:
Very disappointed with this service. When I registered there for the first time in my life they have ask my right after the registration to confirm email and complete verification without mentioning on the main page that they will charge money for that. I have never seen any verifications for money in my life before so I was not vigilant at that moment. When they ask for a bank card data for the verification I was surprised but explained to myself that this is how they push users to make inner purchases in future. I did everything fast and mechanically as many of us do when fill up a bank card details and after I already pressed OK I mentioned a small sentence with a price above (it was regular info sentence with with the price that was not marked). I really didn't see it. "My fault" - was my first thought - "But no worries, they seem to be a noble company so they will return money for sure" - was my second thought. I have wrote them right after I did the mistake and explained everything to them: that it was an accident and I wrote them the next moment after I was charged. With big unpleasant surprise I have received the answer that they do not do refunds (I wonder is it actually legally?). I wrote them again and said one more time that it was really an accident and I am not even sure that I will use their service at all. No answer was after that. So I called them thieves and was truly with a big awful first impression from them.
Hope, you will be more careful.
