I had Colorado Interlock install a Intoxalock on my vehicle and the technician stated he would refund my money if I did not want to keep the device. While driving my car, sometimes the device would go off every 5 minutes. I called the main office and was told that is how the device worked and that I was being tracked with a GPS on the device. The GPS would be used to alert the police if the device registered alcohol. I then called and scheduled a removal to have the device removed from my car the following week. After the removal, the technician would not refund the two months lease and calibration charges I was told would be refunded.
