This person called me 7 times today, starting at 8:38 this morning. Talked to him last time he called (I ignored the other calls) and asked him why he called so many times. He thought he was trying to make contact with someone else with my number and said that the calls were automated. He said he would take my number off the list and that I wouldn't receive any more calls from him. I told him that I was on the "do not call registry" and I would report him if they called again. His response was "Oh, ok". So hopefully, he took me seriously and will not call anymore. I feel like I got through to him. Very annoying.
