Bad service and attitude

The security that works at night in Tirong Estate at the residence gate is very rude to the residence. He's always talking with his friends at the gate which causes problems and makes other property owners not to be able to go inside. We must wait for him first to finish talking then go inside. When we ask him to ask the people he will talking to move the car aside so that we can go inside. He says we not teach him his job. I wanted to have ADT services at my house but due to this kind of behavior and response we get from their employers I'm not sure if i will still consider using them.
