Went to get an $800.00 alarm installed and after installation, my door locks kept locking and unlocking on their own as I drove down the road. My door ajar light stayed on as well. First they tried to say it was my truck at fault. Then they unhooked the alarm and everything worked fine again. When I tried to get my money back, they said NO. They can't guarantee that my truck wasn't doing that before I brought it in!!! REALLY???? Now I have to spend more money to take them to court, but just wanted to save anyone else who might be reading this from going here and losing money!
