Official results will be published within 7 days after each tournament.
The first five players gets VIP/DSC status (10-6-4-2-1 days), in case there were at least 20 participants.

Most of the time that VIP is distributed either by or on the 7th day since results being finalised. If it's delayed then i guess it's due to staff not having enough time to manually distribute it accordingly.

I still didn't get VIP status, i won tourney 8 days ago, when i will get it??? 

Sadly there's no way to give a specific date and time as to when you will recieve it. Sometimes it's delayed, sometimes it isn't. Not much you can do but wait honestly..
