Russian rubels didn't work too!

So, i live in Ukraine which uses "Hryvnia" but i changed it to Russian Rubels and i bought a ton of stuff. Today, when i was donating again, it just showed me "Unknown Error".

P.S Got answer from Steam Support:

"Due to recent changes, in order for you to be able to make purchases on Steam using a credit card, now you need this payment method to be registered in the same region in which it is used.

In this case, in order to use a bank card on Steam in the Russian Federation, you need to have this card also registered in the Russian Federation."

Buy steam gift cards and gift them to your account. How hard is it to understand?
