    I setup a time and install with Guardian Interlock in Colorado Springs service provider at 3505 E Saint Vrain, 80909, 719-597-6495. They checked my vehicle and had me sign for the install and equipment to be installed. Patrick, the installer, had the services in my vehicle in less than 30 minutes. When I was showed how to use the equipment; please bear in mind that it's already been installed, I couldn't blow hard enough or long enough to pass. There was no questions and/or discussions in the documents or from the service tech about breathing difficulties and/or lung problems.

    No one ever stated that there was a unit in the office that I could test on to make sure I could use the equipment. I was then told I needed a letter from my health physician stating my copd, asthma, etc.. So , I called my doctor and he emailed a letter for me asap. I showed them the email and I was told that wouldn't work, that there was a form that needed to be filled out prior to the install. HOW WOULD I KNOW THAT? Nowhere at any time during my appointment set up was I asked about breathing difficulties from the Guardian customer service or from the service provider.

    I needed my vehicle so I requested the equipment be removed. Then I was told by the service provider, it would cost me $250.00 to remove it. Please bear in mind again, I'm still at their facility, it took the tech all of 10 minutes to take it out. I do not feel that I was treated fairly, and I do not think that the service provider was upfront or honest in their dealings. When I suggested there be equipment set up in the office for pre-trial to make sure the customer could operate it, the tech said there was, but that I didn't ask about it prior to the services. What the hell?

    I called the customer service number and was told the same thing. All my fault that I didn't ask prior to the services. I am very dissatisfied with the company, the services, the equipment, the service tech, Patrick, and the way I was spoke to and treated. I'm a 60-year-old male, not a stool pigeon. I would not recommend guardian's services to anyone especially if you want to be treated fairly.

    Customer service is horrible. Hector especially was bad with handling my situation!! They said no payment for first month and was charged right away! Then the device messed my car up and they won't reimburse me for the money spent to figure out that their device caused the car issue but I have a receipt from the mechanic and still nothing!!

      Guardian is lucky I got one star! The devices are junk and don't work properly! In 1 year I've had 5 different devices and the current one isn't working right either! Junk! It has caused me to miss work multiple times, have to pay $120.00 for a tow because of the junk device. They charge $125.00 a month which is way too much for the junk they call interlocks! Horrible customer service. You wait for hours to speak to someone and even then they are clueless! Worst experience I've ever had with any company period! Avoid Guardian at all costs. The free installation doesn't make up for the hassle and money lost because of this horrible company! They don't care about anything but lining their pockets with money!

      Worst interlock on market. Bulky camera falls off windshield while driving. Cord keeps coming unplugged from device. Beeps to blow every 15 minutes. Aborts blows and flags blow not strong. A kit some genius 6 year old designed and sells on temu.

      Scam artist. Was defective equipment. Car equipment malfunction over five times and still can get it fixed. Haven't been stuck multiple times. Customer service is horrible. Supervisors do not answer the phone. Do not go to these people. You will be surely disappointed and robbed of your money and dignity.

      This company is the worst. Anytime you need to get ahold of them you’ll be on hold for at least one hour. The shops they use are very unprofessional. Their customer service has no idea what’s going. It’s like they just read a response and can’t think outside the box. Terrible service. They’ve charged me for the wrong date and always mess up the appointments. Always late and never answer their phones or return phone calls.

      I recently had the pleasure of visiting Guardian Interlock and and I must say, the experience was outstanding. I can confidently say that their service is top-notch. The store was well-organized, and the staff was friendly and helpful.

      Staff are rude and unprofessional, they treat you like you're worthless, they don’t give any useful information nor help in any way to resolve issues with their products or services. They charge unregulated fees. Your punishment never ends with these parasites. A class action is needed.

      Guardian Interlock are being run by an incompetent thieving scoundrel. They are not in any way earning an honest dollar. Their goal is to take even more of your money by installing a ridiculous unsafe device into car which will no doubt incur you more costs than just your normal service fees which are pure theft also. (5 minutes work = $130 per month). If you need an interlock installed do not use guardian interlock. There is no way possible that the other interlock providers could possibly be as inconsiderate and as much of a disgrace as this Guardian company. Take my word. The boss in Sydney is a gutless coward earning a living by ripping people off!

      Dealing with Guardian Interlock was the Worst Experience of my Life... I was only required to use device an IID for 6 months. Upon completion of my 6 months, I contacted Guardian to send me my release paperwork. Guardian Interlock HQ refused to release my certification of completion to the courts. They added 2 months to my time with the device in my vehicle and made me pay for those additional 2 months of fees. I called their service line everyday for a month and was constantly hung up or transferred to a dead line. All I needed was one simple release form. I never raised my voice or was rude, their customers service department just acted this way.

      After a month of this, I eventually contacted my attorney to deal with Guardian and it took my fabulous attorney over a month to receive the release paperwork to remove my device with the courts. If my attorney had not taken mercy on me and done this work pro-bono, I would have been stuck with an additional $1000 bill to receive a simple document. Yet, I still had to pay Guardian for the extra 2 months of the device. How can this be ethical? AVOID THIS COMPANY AT ALL COST. All of these stresses will COST you money. Shame on you Guardian, you have been in business for 35 years and never been BBB accredited. Want to guess why???
