Chess Blitz: No forced draw?

I played someone and forced the same position over and over, who then in turn repeatedly refused draws. I finally just gave up and decided to chock it up to an actual draw, because that's what it was. In Blitz there's no way to force a draw?

There is in real chess, but not in the RHP Blitz implementation, which is something almost, but not quite, like chess.

I came across this myself a while ago. As you say, claim it as a moral draw and move on.
