Have received calls from this number Monday through Friday in the A.M. for the last several weeks. They disconnect after 3 or 4 rings and never leave a message. I DON'T do business over the phone with unsolicited callers and I've asked these people to stop calling and I will not pick up when I see the ID. I also am registered with "Do Not Call" but understand that non-profits are exempt but this does constitute harassment when they're asked to stop calling.
