How can I cancel and refund a flight?

I booked a flight Moscow-Amsterdam-Seattle departing on 26 June at 5:40 am from SVO, Flight Confirmation # HI3PVJ. There was no warning on the DELTA or KLM sites that being a Russian sitizen with no US citizenship or Green Card, I am not eligible for the flight. I was planning a two-week trip to visit my sun Dmitri Leonov and his family who are US citizens residing in Seattle. However, they have found out and informed me that I cannot board a flight to Seattle in Amsterdam according to current US international flights policies. If it's true, I would like to have my flight costs refunded. What shall I do to get my money back?
