I live in Fayetteville, NC and I was previously an Alcolock customer. Since my company was changed to Monitech, I have had a very difficult time with the representative at your Fayetteville location. In the beginning he expressed very clearly to everyone in the office and myself that he was the only person working there and was very overwhelmed because he had a lot of installs from Alcolock in addition to his regulars. I went a couple of times (on my scheduled appointment time) for recalibration and it was the same experience. Appointment times were never honored and always there were others ahead of me. I went in one afternoon and having other appointments after, I told him that I had an appointment time. I was trying to also let him know that I wasn't a random walk-in and I was hoping he would put me ahead. He quickly became defensive and responded angerly, to which I responded angerly. The conversation escalated and in the end, he threatened to call the police on me, said I wasn't allowed back at the Fayetteville location, called his boss & said in front of me that I was one of the alcolock people and I always have an attitude. Most of our conversation was held while he was actively on the phone with his boss, so I hope there can be a more factual telling. If not, I hope the surveillance cameras are working and I'm asking you to please, please review them. The man is very unprofessional & inappropriate. He calls me "Love" instead of my name and I've asked him not to do that, as I am married. My last visit there he told me I would need to have an appointment set so that he could convert my "contract" from court ordered to voluntary. I chose to keep the breathalyzer for a year as I am in active recovery from alcohol and feel safe with it for now. He also said I would be charged a late fee, which I wasn't. I had rescheduled my appointment but I did it through a representative on the phone. He asked if I could come back the next morning at 9am so that he could discuss with his boss the proper steps to take. I agreed, reluctantly. The next morning I showed up at 8:50am & there were already 6 people waiting in line ahead of me. He was also late that morning and didn't show up until close to 9:30am. I did not bother going in because I already had anxiety about dealing with him again and I knew I would be waiting forever. I called and rescheduled the appointment for this past Monday in the Durham, NC location. This is an hour & 20 minute drive for me but honestly it's worth it. The gentlemen that ran that office had me in and out in less than 15 minutes. I couldn't believe it. He never said anything about late fees, said there was nothing but computer updates with DMV to switch me to voluntary & he gave me 2 free pens! I wasn't going to post a review about the Fayetteville office. But after the experience I had in Durham, which btw was a one employee office as well, I felt like I was obligated. My apologies for the length of this, its just been a lot. Thank you

This machine sucks. I don’t even alcohol for 18 months and still lack the system just to go back to pay $75 they can’t unlocking

We appreciate your feedback. While device settings are set by state regulations, our team works hard to train customers, so they feel confident using the interlock. We continuously test devices ourselves to understand the experience better, and feedback like yours helps us improve our support and training resources.

It should not take a week to get an override code sent to a mechanic to work on a vehicle. I've spent hundreds of dollars on rides for a week waiting on your company to send the code to now finally have them be able to start fixing my truck. Other companies are able to supply the code in an hour. What is the holdup?

At 9 at night on Saturday a very kind lady helped me get an appointment to swap out my device from my truck to my car. I'm so thankful for intelligent people who can do their job with a great attitude. Now If you could just lower my rate.

I am updating a previous review. (Runrunrun) Since my experience their customers service has reached out several times, unfortunately I have not yet had time to speak about the situation with the guy that did my installation, everything else has been explained, and a credit to my account for the install fee. Each time I have spoken to someone over the phone they have been very efficient in fixing and explaining everything. Their customers service has been awesome. How ever, that still leaves much to be desired from their installer in the Highpoint NC, location on surrett dr.
