Yes. U need to call them request for putting u on wait list. U can try to call them very early in the morning or late night and it could reach them more easily.
Personal sharing - if u doesn't want to wait so long for the hotline, pls call at night and choose 'english'. After the customer service pick up ur call, u check if they can speak Cantonese. It works!!
