Have been receiving calls almost daily from this number for several weeks. Caller ID says calls are from West Jordan, Utah. When I answer no one is on the other end. Received call today and live person on other end. Claims to be calling about solar energy. Says they are not selling anything but if I qualify they will give me a free solar energy system. I just need to answer a few questions to see if I qualify. Of course, I did not. I told the man I was on the National Do Not Call Registry and I wanted to speak to a manager. He claimed none was available. When I told him he was breaking the law and I would never do business with a company who breaks the law he hung up on me.
