B-TICKET 订乌菲兹门票，已扣款，没收到确认信，

1/5在b-TICKET 订了两张乌菲兹门票，招行已扣款。当时网页提示如下：

Your purchase is complete.

You will receive confirmation of payment along with your voucher by e-mail in three working days.

Come to the ticket office with your voucher and some identification no more than 15 minutes prior to the time of entry.


但我到现在还没有收到voucher。



现在要怎么办呢？
