Net star- a total *******

Last Wednesday , my vehicle was ******. The vehicle had a tracking device fitted in 2013 by altec netstar. When I immediately contacted Netstar's regarding the theft of my vehicle and asked for my vehicle to be tracked. I was told the next day when I called that they could not pick up a tracking signal and informed that the vehicle couldn't be tracked when stationery and only when in motion , this was not communicated to me upon entering the contract. After which I requested netstar to show me a report of my vechicle whereabouts prior to the theft they could not meet my request with no reasoning. So my question is why did I pay a subscription when it appears that my tracking device never worked in the first place . Furthermore , why was I not contacted to have my device upgraded after 3 years of having it fited or my tracking device battery replaced. Netstar's response team got back to me 4 hours later ( 10:30pm) the vehicle was ******, who were they fooling and what were they looking for ? Were they looking for a needle in a hay stack. Did they even look ?i was under the impression that I signed up for immediate response.
