NO DELIVERY OF SERVICE

I moved to Discovery Insure on 1 December 2015. I made an online appointment (and phoned to confirm) to have a sensor installed in both cars insured. No one arrived for the appointment or contacted me to cancel. I phoned to complain and arranged for a second appointment. Again I was stood up and again I was not phoned to inform me. When I phoned the call center I was told that they make use of a service provider and cannot be held responsible if they do not arrive.<br> I fear I have made a mistake by moving my insurance to Discovery! If this is the kind of service they deliver I don't want to know what kind of service to expect should I need to claim!<br>
