"I just wanted to take a moment to give a huge shoutout to Bill, who helped me over the phone with my Smart Start interlock device. From the very beginning, he was patient, professional, and incredibly kind.
What stood out most was how understood and supported he made me feel. Navigating something like this can be overwhelming, but Bill explained everything clearly, answered all my questions, and made sure I felt confident moving forward. He truly went above and beyond to help me out.
It’s not often you come across customer service like that these days. Thank you, Bill, for your outstanding support and for making a stressful situation so much easier to manage. You made a real difference!"
