Let me tell you about an RKC. I don't know what they get put into them, but I am here to say, they got it. Each time I address one of them, I get a direct response. They always answer me. They are always polite. They always have led me to where the information is I need. They just have never let me down. If you have any doubt, or want something ironed out, check one of them out. They are an incredible human being and I'm going to be one of them also.
