Dear LingQ Team, how am I supposed to pay for the premium?

Dear Lingq Team,

Unfortunately, I have not been able to use the Lingq Premium due to the fact that it is simply impossible to pay for – there is just no option! The web version only has PayPal and Visa/Mastercard stated as the possible ways of payment and my last Visa card expired a couple of years ago, banks here no longer make Visa/Mastercard cards, the only option is МИР cards. The mobile version (Android in my case) does not even let me log in to my account: after typing in my correct login and password it just loads infinitely.

Could you please provide us, the Russian, with some solution? I want to use the LingQ service really bad but it is not possible due to the aforementioned issues.

Thank you,
