Audio and video installation service near Barrington, IL

I had a remote starter installed by this establishment in my brand new Honda CRV six months ago. I had nothing but problems with it. I made total of three visits back to have different issues fixed. My latest problem is that the system sucks too much power from the battery. If the car is not driven daily, the battery dies. It took a while to detect this problem since I usually drive every day. When I went back today, I was told that they will look in to it but they already know that remote starter is not to blame for this problem. I have consulted couple of reputable auto mechanics and they pointed remote starter as a source of my issues with the battery. Since this is not my first issue with Mobile Audio and because of their rudeness and lack of professionalism, I did not let them touch my car again. I will be going somewhere else to have it removed or replaces. I did file a complaint with BBB against this very shady place. Stay away from them!
