Negligence and poor service

Terrible experience, security gaurd negligent which resulted in a loss of my assets. Claims department rejected my claim against the company, they believe claim everyone acted in a suit manner, while due process was not followed. SAPS statement, ADT statement where the gaurd is stating his failure to properly authenticate a client. He responded to the alarm found a truck outside my yard and used the ********* cell phone to speak to another ******** claiming to be the owner of the house. No record of call, however the head at claims department says that's a suitable manner... Pure negligence
