Is it safe to leave your children at the active fun play area? Specifically at Megamall?

I suggest NO.. In my experience I left my kids in the play area,I'm just 2 stall away from them and when I get back they're gone.I was horrified when I saw them outside the mall.The staff said that their time is out that's why they let the kids go out to give way for another children whose waiting for their turn..
