Nelli treated me very good,she took care of everything for me

After writing a horrible review concerning the service that I received on the installation of an interlock device, I was immediately contacted by the Area Manager, who apologized for the poor service indicating that the shop I had been to was in need of further training. He authorized a refund for the full amount that I had paid and I received the check within a few days. Obviously, Guardian has great people working for them; so the lack of understanding the equipment lies solely with the contracted technician.
