How can you trust this service

Found my garage door open when I returned home after Chubb had called me to tell me my alarm had been activated.<br> I called them and asked them how could they have missed my door open flapping in the wind?<br> They sent a man to investigate. He took pics.28/12/2015<br> I waited for feed back.<br> I tried to log in a complaint on there Web Site....No luck<br> Spoke to the man in charge, real bad attitude Mr Dollie <br> Said that it was his best man.....What would have happened if I had beed ****** would the insurance pay me out if they the said Security Company did not infact see that me garage door was open????<br> What bad service ! How can you put your family's care in there hands ?
