NETSTAR TRACKER FAILED ME AS A CLIENT

I utterly shocked and disappointed at the same time.

I got my insurance with Dot Sure and they advised me when I took the policy tracker is included, On 06/11/2019 our Polo Comfort line was ****** between 06.30 & 07.30 PM. Tracker never picked up someone was tampering with the car. We were never contacted to advise accordingly. Also they never informed us the car was travelling out of range. I need answers for this it very disappointed. HOW DID THE THIRFS KNOW WHERE THE SMART BOX TO DISLOCATE AND TAKE OUT. ALSO WHY .....WHY WERE WE NOT CONTACTED BY NETSTAR. I HAD THIS VEHICLE WITH OTHER INSRANCE FOR 7 YEARS THE CAR HAD NO TRACKER NO WE CHAGED AND INCLUSED TRACKER AND THE CAR GOT ******.
