Poor Service n lack of response

We had an attempted break in 3 weeks back. Two days after the incident we went out it was a Saturday. While we were out we got a call from Chubb that the alarm was going off at home. My husbands asked that who ever goes to the house to check they must go into the yard to check thoroughly as we had an attempted break in. We rush back home. On arrival we saw the chubb car outside the house and the guy was sitting in the car. There was a note he stuck on the gate that a front check was done( meaning he did not go inside. My husband left me n the kids inside the car n went in the yard to check. We atleast expected the chubb guy to go in with my husband to assist but he carried on sitting in the car and just drove off. I called and reported the incident and I was promised it was going to be investigated and I will be called back with feedback. On the 4th Sept I called again and left my name n number. Up until today no one has bothered to call me back. I wonder why we keep on throwing our money down the drain by paying chubb each month.
