“A round ends when one player plays the final bone in his or her hand, or when the boneyard is empty and no player has a valid play.” - THERE. That’s the rules that’s just been quoted at me. The round ended there and then when I placed the last bone in my hand. It should not matter the amount of bones or pips/dots in the opponent’s hand, the only thing that should matter - they had SOMETHING left in their hand. They should have had a point.

The rules to me are clear, and the game did not go according to the rules, so I would liken to escalate this matter further - how do I go about it?
