Humiliated

I have had the worst experience with this company. I had a tracker installed last week and wednesday as I wanted to leave work, my car would not start. The 1st thing I thought of is the tracker because the technician didnt look very experienced and i asked him if my car will drive the same. I managed to kick start the car got home. The morning didnt start kick started again, got to work called maybe by 9 or so they said someone will get back to me and no one did, the lady also said that it's not the 1st time it's happened there are a number of people complaining about the same thing, I tried calling several times and same result no one can to check the tracker out, I had to find a way to get my car to start. My whole work day was messed up as I was not as productive as I would be because I was stressing about this matter. This morning I am unable to get to work and I have called again and now been told I have to call the scheduling department and they open at 8. I wouldn't advise anyone to install a tracker with this company.
