I get false positive blows that make it that I have to get the breath analyzing device re calibrated which costs extra on top of the bi-weekly fee. The machine said I blew .386 and car started honking I pulled over turned the car off then waited until the device cleared and I blew again and started the car up to continue on. I called the customer service and they said nothing they could do I had to pay the recalibration fee on the next bill. That’s 86.00 on top of the 146.00 a month I already pay. This company is the horrible to have to deal with. It’s my fault for being in this position but I don’t deserve to be miss used like this company does.
