I asked the Play Market staff to keep a better eye on the products on their site. I have been a user of this service for over half a year.When I got really Tired of bad program functioning, I decided to refuse its services. But I wasn't able to do it myself. The support service didn't react to my request,and I had to turn to the bank. Only there I was able to unlink the subscription from the card. The operator ignored me for a week without any response.
