Intoxalock review: Customer service

I took my work truck for calibration. The calibration machine broke and my unit would not start my truck. I was told to call intoxalock for a mobile technician to bring me another. The other services stated he would not travel that far. My servicer received the replacement in it today and it failed to program 4 hand units he had. Intoxalock is sending him another machine. Meanwhile I call Intoxalock and ask if I can pick up the hand unit from the mobile tech who would not travel to me and was told no the vehicle had to be present. 2 days of missed work. 1 hour and 42 minutes on the phone and no resolution. Worst customer service I've experienced.
