Abused by security guard at the restaurant

Query with the manager and staff that were being rude to me to a point the security guard that was on duty also fought with me laughing at situation and slaped me two times. I got my order and because he was heating me my hot wings spilled on the floor and if I ask for replacement the manager refused. I felt so useless as customer, those people don't know how to treat, there is no customer care at all . The name Of The manager is Muzi
