After getting all these calls with no messages I finally picked up. Someone with a strong accent said they were "college advisors" and wanted to talk to me about going to college.
I pushed #2 to speak to someone about 'educational opportunities'. Wished her a happy Mother's Day and asked if she had heard about the National Do Not Call List...she said yes. I replied I AM ON IT and DO NOT CALL ME. Sounded very quiet, almost timid. I further said that the next person who calls me will have the police at their door. She did have my number, which means they have caller ID.
