This absolutely terrifies me what company is able to do to players and still get away with it. They are completely free to lie around as they wish still without any consequences. It's irrelevant what has been announced after the event. Bonus day was supposed to take place for full weekend and as such had to be fixed.
Every serious company would have apologized and fix the problem. This is one of the biggest fraud they pulled on people and they keep going like nothing happened.
