sometimes it is hard to believe but  nothing that we can do mate, I am with your own position also when there is a great casino that I wanted to play but they are not allowing my location to play.
I think you can try contacting their support if there is something  they can do for your case ? but not sure if it is allowable by any case.
and yes if you have not played in roobet then you missed once and a lifetime chance because of their greatness and providing better experiences to their players.
