Fnb powerball

I have spent thousands of rands on powerball trying to win the jackpot .tonight at 8.18 pm I get a message that the deadline is now 8.10pm and not 8.30pm . I can not find any correspondence prior to this advising of the change . Please correct me if I'm wrong .if not this could cost me or others millions in lost jackpot if our numbers come in . If no communication I suggest that whoever made this decision is in the wrong job !!
