"Donny was great! He was patient with me and expressed a genuine desire to make me comfortable in an embarrassing and uncomfortable situation. He answered all my questions, and made sure without even a dollar he could get me set up in the system that I need to sign into. I literally used all my current money to get my truck out of impound of 3 days...$487.00. Sooo most grateful for a dollar lent. Great customer service skills! "
