One of this companys trucks blew through a stop sign and almost hit my mother and my two year old daughter. He was speeding. When my mother called and asked to speak with the owner, she got no response. When she asked who was driving the red truck in that area, she said it was their salesman Ray. What idiots. No call back. No apology. They could have killed my daughter.
