I have had my interlock for 15 months. For the most part everything has been great. When it was first installed I had many problems with it, leaving me stranded for hours at times. The owner did eventually call me and give me a credit for one month, so I guess they made it right. Since then everything else has been easy. Been to three of their locations and staff has always been nice or at least not rude. Normally in and out quickly.
As I mentioned I have had my interlock for 15 months, I have never missed an appointment. Nor have I ever had to reschedule without giving them their 24 hour notice. Today I went in to get my monitor serviced, my car has been running poorly so I had someone drive me up so I could take my monitor to be serviced. When I got there though they said my vehicle had to be with me for an inspection. I explained that it was being sent to the dealership tomorrow to be serviced. They told me they could not complete service without the vehicle being here then directed me to call the main office @ 888-717-8278. When I called I got the "pleasure" of speaking with Tony, the on shift supervisor. I explained my situation and he told me that I would be charged a $25 fee for a same day reschedule. Again I explained my situation to him and asked if he could help me out this time. And since in the 15 months I've had my interlock I've never done a same day reschedule and before this visit, and no one has ever inspected my vehicle. Tony proceed to tell me it's policy, I told him I understood, but pleaded that I went out of my way today to get my monitor down here today and if I could just get my appointment changed by one day or anything. After going back in forth for awhile Tony started telling me "whatever" and was extremely rude.
Long story short, I would have recommended this company until my encounter today with their floor supervisor.
