This matter is now solved!
I like to note that I am very disappointed by FA - I really did not expect such unprofessional behaviour.
Shortly the story is like this:
1) I was supposed to be paid November for my earning - it did not happened so I guessed that may be they increased their minimum pay out and did not managed to publish it on the site so I decided to wait.
2) December I was supposed to get paid it did not happened again. I wrote an e-mail to a guy called Ruaan and he said that the reason for this is that they stopped paying by Neteller in Bulgaria. Which I think is complete bullshit because Neteller is fully functional in Bulgaria and I receive commissions by it without any problems. Anyway, at least somebody could informed me about it.
3) I wanted to add bank wire but it appears that this is not available in Bulgaria as well - I have no idea why because Bulgaria is a SWIFT country and it should be flawless.
4) Finally I needed to add EcoCard (although it looks very inconvenient for me) and asked Ruaan to confirm if it is OK. I asked him twice and for three weeks no kind of answer...
