Message them on FB describing the situation, it usually takes them a lifetime to get back to guests (even more so now, given that everybody's probably panicking and thinking they will somehow be better off by cancelling travel arrangements), but clear communications and persistence tends to work.
I would also do that later when you see the actual points for the second stays posted - there is a slight chance this might work out well without further intervention, plus all they can do is correct post-factum anyway probably. The workload on CS reps may also be lighter then.
