Fitment gone wrong

Good day, Hope all is well. I have serious problem with Netstar, they installed a Tracker on my Car on the 25th of May, ever since that day my car doesn't want to start and my radio went off, I took the car to Ford to check the health of the car, battery charging, alternator, everything was fine but there is something drawing power from my battery and I told them I had a fitment few days back from Netstar and they said they won't get involved if its a Tracker. Thursday 1 June the same lady who installed the tracker came to check what's wrong with the Tracker and she told me there is nothing wrong with the tracker and told her you can see my car doesn't want to start, so she jumped my car on the same day, Friday 2nd of June I only noticed that my car is sitted with 3 trackers, she never removed the existing 2 trackers that were cancelled to my surprise the trackers were for Netstar & i dont know why she never picked it up that these 3 trackers are drawing power from my car, I got a call from one of the Netstar Agents around 3pm Friday scheduling with me that they will send a Technician on Saturday 3 June, 1pm , to my surprise the Technician never pitched up. This is unprofessional, I called the Emergency number around 1:30pm and I told them um waiting for a Technician to come & I was told there is no Technicians who work on Weekends, haaibo why would you schedule with me for Saturday knowing exactly that no one is coming. What an inconvenience. From Netstar I need my battery that you damaged because of poor perfomance, i went to buy a new battery worth R1850 because of a foolishness that was done by this unprofessional technician of yours....
