Disappointing customer interaction

My husband's vehicle was involved in an accident October 24. I was informed by tracker i wasn't privy to any info as no instruction was provided to give any details to me despite having been registered the primary driver. I had received an sms that there was battery failure and even after that confirmation they still refused to help. I then obtained police authorization to get information from which i was told the car had last been tracked on the high way around the evening. We found my husband dead 2 days later and my argument is that since this vehicle had a power failure and had not parked at its primary parking spot for 2 consecutive days was that not course enough for the tracker to get someone to investigate it's whereabouts?? What was the point of having the tracker installed in the first place if the car can be out of range for so long and not have anyone do anything about it?? If you'd done your job we would have found my husband the night he died and not in a government mortuary days later. You are an inhumane and heartless bunch of leaches solely interested in collecting debit orders.
