I think perhaps beta testing is not your strong suit.
That is not about Beta testing. Its about telling for one Week now "its coming tomorrow" and than they don't get the Job done. But they keep messing around with the Fans by telling them the same stuff over and over again. After a Week of this behavior i would first look at the Clock if they say "good Morning". If i would work like this my Boss had kicked me out of the Door a long time ago.
