False advertising

I joined the Virgin active Red on 4th January 2018 and they are running a special that if you join the club between 1st- 9th January you get a free virgin active bag. When I ask the consultant there, they act like they don't know. Even on their Instagram page, Virgin active red still advertises. I would like to know, why they are doing false advertising. And would love to get the Virgin Active bag. Some people are getting it but I was told that there's no such. I'm at Virgin Active Red Durban CBD
