Since the casino didn't ask for any of that,  you have to take a chill pill and wait to see your withdrawal getting processed and reflected in your wallet,  I guess you are good to go since your withdrawal request was accepted by the casino.

If I were you waiting for a day or two won't be a problem considering the amount you are expecting,  and there won't be a need for frequent follow-up,  all you have to do for now is to wait.

In a couple of days, we should be able to get an update from you,  and the outcome of that is what will determine your next position.
