jessi dear,
for your info i applied on 15/2 and get the membership number on 4/3
so it may take 2 weeks+
if you do not get your membership number after 2 weeks, can write to them thru Just-VanNess official website:
1. click on [contact] (at the left bottom part of the homepage)
2. there are 2 boxes: 口會員編號 口不是會員, check the 2nd box不是會員; then pick [我沒有收到...](I did not receive....) at[詢問主旨](subject);
and write your message in the box below it;
3. click on [送出]to send out your inquiry.
hope the info above is of useful to you
