They said that this wasn't a sales call and that I had been referred by a friend or family member to get a security system. Added to the block list on my phone.
This number calls about 3 times in a day and about every two days. Does not leave message and if I call back, it says the number is not a working number. One time my wife answered my phone and told the man who was on the other end to quit calling, she was going to report them. They stopped for about a week, then started calling again.
