Account transfer to Russian server

Hello, I am live in Russia and I want to transfer my account from EUNE server to RU server. But I have not enought RP. I wanted to buy RP in store, but when opening page with payment options there is no payment options for Russian Federation at all (due to Russian laws). So, I even cannot buy RP. How can I transfer then? Created support ticket, passed 3 days and still zero reaction - task is even not assigned to anyone and not even boilerplate response.
