hawaiianwahine Yesterday? As in August 31st (using GMT+8 because it's what WN use as their standard system time)?
If that's the case, then your privilege access may have expired not long after you bought it, because they always expire at the end of the month at 00:00 GMT+8. This is explained in the privilege page and rules.
Never, ever, buy privilege at the end of the month. If you really want to buy it, you should ALWAYS buy it at the beginning of the month.
