I think in this particular case you guys should comunicate with the engine support team directly via email. What a lot of developers with complicated country financial systems do is simply create an offshore virtual bank account to receive and send money. I will not post specific links, but there are lots of banks in the world that provide this services legally.
So in your case you could receive money on that account, pay Epic if needed and then transfer the rest of the money to your local bank accounts.
Take in account this is NOT legal advise, please check with your country laws before you do anything. Also most countries do have special regulations for exporting services and goods so they can send/receive money from/to other countries. Always check your local legislation.
