Kiddies playing area left unattended with no employees in Seven Eagles Spur

Seven eagle Spur in greenstone shopping centre don't have employee to look after the kiddies playing area, my daughter got hurt by a machine which is there by the kiddies playing area, the ball dropped on the floor under the machine, some kids tried to lift up the machine and asked my daughter to get the ball, none of the workers were around to help and supervise, so my daughter's arm got hurt with big blue mark, really don't know how can the restaurant allow the kiddies playing area left without employee to look after the kids. Will definitely not visit the restaurant again.
