Sorry I can't give them 0 star, Used this company services 2 years ago to install 2000.00 dollars in equipment on my 2014 Silverado Truck. (Clifford Alarm, Pioneer Sound System and Back up Camera ) Unfortunately I lost my receipt and I'm having trouble now with Alarm System, which is still under warranty. I just gave them a visit and they state that since I lost my receipt they can't help me, but the most unfortunate part for me is that there is no record on their system about my installation. How is that possible? I have the Alarm system brain in hand that shows the serial number, they state there is no way to know if I bought the Alarm from them. In other words they do not keep track as an authorized dealer of the merchandise they receive from Clifford, please avoid this company to do business.
