Car track is dishonest and not reliable

King price insurance refuses to pay my car claim because of car track does not want to take responsibility of furnishing them with full accurate report of my VW Tcross car movements and also installing a 2016 SVR unit on my vehicle whereas i was owning a 2019 model. car track told me that the device was working when my husband got hijacked with my car in May and i had increased my premium to ensure that they maintain my device when it is faulty. Now they gave the insurance company different reports that the device was faulty then again it was working, Can someone please get someone who knows exactly and is willing to explain how that SVR device works.I have being paying cartarck for many years but only get a dissapointing service.
