Thank you for sharing such kind words about Dylan. Exceptional service is what we strive for every day and knowing that your experience reflected that means a lot to us.
Well very strict payment situation . Although in my distress and clear description of help I needed. They do listen, and care to keep us on the road. Just be kind, respectful, they have a busy job . And actually are very quick to answer. Never on hold long...
We truly appreciate you highlighting Ric. Our team takes pride in providing excellent support, and it’s great to know their efforts stood out to you.
I encountered a false lock-out, and the technician provided a code so that I could get to the service center. When I got there, they fixed the situation, and there was no inconvenience charge. Thanks.
Thank you for sharing your experience with our Severna Park, MD shop. We are so pleased to hear that your visit went well, and we have forwarded your review to our regional management team so they can celebrate this success with the staff!
I probably had the worst experience this past month when I was locked out of my car after I had already did my calibration appointment the day before. I missed out on work. I wasn’t able to take my kids to child care.
We’re so sorry your appointment wasn’t the smooth experience it should have been. We’ve shared your feedback with our field management team, and someone will be reaching out to make things right.
Great Ron was informative and such a pleasure to talk with him
Hi, we appreciate the kind words, but you left a negative rating with only 1-star. If you meant to gvie Ron a good rating, would you please update your rating on this review?
The customer service is top notch. Very helpful. I can call anytime and they answer quickly. I thought the closest center to me was an hour and a half away when it turns out it’s around the corner. Thank you!
We’re so glad you had a great experience with Selene. At Guardian, we know that every interaction matters, and it’s wonderful to hear that their support made a difference for you.
Fraudulently charged me and threatened me to try to force me to pay for a broken product that never left the installers. Sent me to collections, and thought I was stupid enough to pay for an alleged debt that they knew they couldn't provide proof of. Nothing but a load of crooks trying to kick you while you're down.
We show you as a current client with no collections notices or delinquencies on your account. We believe you may be mistaking us for another company. This review is for your interlock provider, Guardian Ignition Interlock, and your local provider is J Morris. We'll be in contact soon to try to clear this up.

My operater did everything and then some... I came for a quote expecting a hassle because I've had it happen with more companies but he made it not only a great experience but a relief with certain life circumstances happening...

Fast and spent time with me to use the interlock
We truly appreciate your kind words about the Lakewood, CO Guardian location. Our technicians and partners work hard to support our customers, and we will make sure your feedback is passed along to the local team!
It was hard to talk to someone, kept getting transferred over and over. Finally did get someone - he just wanted me to hurry and pick a day to get this in my vehicle. I was told everything will be free the first month just need to pay calibration fee. I got an email about 66 dollars being pulled from my acct. though it didn't it get taken from my acct., it REALLY rubbed me the wrong way Abbas stopped responding after I got this interlock in my car. If you need to make a sale and wont care after, just say that. You know you'd get our money anyway because most time this device is required by DMV or the state. He was honestly a little pushy but what I can say the store that installs it for you is really great "That email is automated and can't access specific account details, like a credit, to let you know that nothing will come off the card." This is beside the point. The representative stopped replying when it came to me forwarding the email to him saying my card WILL be charged (Again, luckily it didn't) it's just shady contact from your rep stops after everything is said and done.
We’re grateful for your review. Feedback like yours guides us as we work toward making the process easier and smoother for our customers. Please know that you will get an email anytime autopay is due to run because it will still create an invoice. That email is automated and can't access specific account details, like a credit, to let you know that nothing will come off the card. Please know that you will get an email each time, but it will only take money off your card once any credits are depleted. I understand, and we're sorry for the misunderstanding. Sales agents aren't able to help once the device is installed. However, we have even more service agents who are available to help once you're installed. Just give us a call at 800-634-3077.
Friendly staff and they installed it in less time than they quoted
We’re so glad you had a great experience with Solina and our Denver, CO shop. At Guardian, we know that every interaction matters, and it’s wonderful to hear that their support made a difference for you.
