The caller identified himself to me as Keith Wells. Said we had spoken before--NOT TRUE. Just another crooked contractor looking for a victim. Apparently do not call lists are another government joke and demonstration of legislators appearing to be on the job and clueless.
Sometimes someone is on the line, other times it just hangs up. Today, I asked for a supervisor to have my name removed from their list, and the woman said "use some sense, change your phone number". The calls will not stop unless I do that. But if I do - then they win.
