You are from a country under heavy sanctions that have grown tighter, what you should do next is to follow every day and closely what happens in that front, because it's most likely only going to get worse for you and if you are not paying an attention, It's not only regulated casinos that will freeze your accounts. And this is not something they announce in every paper. Just be glad you did got something out.

Sadly only way to get your money back right now is not being a citizen of a sanctioned country.
