Vitality Points not reflecting for Virgin Active Gym Visits.

My Discovery Vitality points are not reflecting for the past 7 days.

I was trying to get to Silver before i purchased an Emirates Air ticket to take advantage of the discount. I'm 200 points away and visited the Virgin active 4 times last week, therefore i should be on Silver. Now i am afraid i miss out on my Air Ticket, or if the flight price has increased.
