Complained to Lego CS again, they basically blamed it all on the marketing team and said thy expect there will be something for Black VIP cardholders for May 4th.
However, they were simply speculating. they had no information of anything being scheduled for Black VIP , but rather said that the marketing team "surely had to do something for May 4th"
I'll believe that when we see it.
I think we've been ripped off
