Yesterday I had the worst experience with the security they hired, they bul**** and manhandled me on my way leaving the mall. I was taken to closed end corridors with no witness to see the brutality and ill treatment for just puffing Vape (e-cigarette) without restricted sign indicating not allowed. They manhandle for just asking why, that's their only reason to embarrassing me during the people on 26/08 on my birthday between 17:45 - 18:30pm
