I called up to Gaurdian and Tawanda did an excellent job of helping me get an appointment set up and give me all the details of what to expect. She was very friendly and informative.

Thank you for the great survey Matthew! Sarah is very conscientious when helping the clients!
I found interlock by Googling it found a $20 off my first month filled out the form put in my telephone number and push submit. And the guy actually called me back about 15 minutes later about five minutes to 5 he was very helpful couldn't set me up an appointment for that day because the place that installs it was close but he did try to call and the next day he called me right back at the same time to set me up an appointment very courteous very helpful.
