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.

Response from Guardian Interlock· Feb 24, 2017
Thank you, Buford, for your kind review. We are happy that our Customer Service agent was able to get you a satisfactory appointment right away. Our agents enjoy helping the clients quickly and efficiently.
Shawnna (sp) was extremely helpful in expalining the installation proccess, made an appointment for me and strongly urged me to call her if there were any questions. However I would like to review the costs as she noted that the installation fee be waived and the monthly fee will be $65.00. I would appreciate an email to that affect. Thank you, Francis
