text: I wish there was a way to give negative stars to this company If only I had checked Yelp before I had my interlock installed I chose them based on their BBB rating which was an A Service was not too bad at first However they did completely screw up my electrical system with the installation I had to take it to the dealer to have it fixed The dealer would not release my car until DA paid for the repairs The dealer called them every day for a week and they did not respond Finally they felt bad for me and gave me my car I do not know if they were ever paid nnAll the previous comments are true device takes forever to warm up In the Phoenix summers this is miserable And you have to do the suck back method which if you do not do perfectly you have to repeat until you get it just right I almost passed out many times from being so winded from doing it again and againnnWhen Guardian acquired DA it was like watching a damaged ship finally sink No one answered the phone anymore it went straight to voice mail The nice flat panel TV in the lobby playing Pandora while you waited disappeared All the employees I would come to know in my monthly visits vanished Then it got uglynnI started my car like always and when it asked for the rolling retest minutes later it said I failed WTF Then it made me keep taking the test over and over and over while I drove home failing me each time It finally stopped beeping as I pulled into my house The next day I get in my car to go to a meeting I am facilitating and it has permanently locked me out of starting my car There is no nice override code like the other places so you can drive in to resolve it no you have to take off the device and have someone else drive you there This is Saturday and they are only open Monday thru FridaynnSo they put the device on their little tester and tell me I refused a rolling retest so they are reporting me to the DMV my contract will be extended for months and that will be Are they kidding Uh no they are just crooks They told me I must have been drinking in the car after I started it or this would not have happened Wrong Then they said that must be why I refused the rolling retest Wrong I did the dumb rolling retest over and over and over until I almost passed out Well they tell me there is nothing they can do Well I tell them then take the device out and I will go to another company Btw the fines for violations prior to the Guardian acquisition were and they raised it to without any notice to customers who have a lease contractnnNow I have a dispute on my hands with the DMV thanks to DAGuardian AND the best part when they removed the device they gave my car a nice long scratch on the passengers side of my Lexus as a parting thank you for my business after I had the car completely detailed days before Not only is this bad business they are criminals
