how i can do it??? 
Hi @mqce,
You cannot purchase Premium directly through our website using Russian payment methods, but you may try to purchase it through our mobile app (your subscription will be active on our websites and in our desktop apps as well):

Please search for articles in Russian that explain how to top up your balance on App Store or Google Play. You should be able to use your account balance to purchase Premium in the app.
