Man called and asked how I was doing without introducing himself. I said 'fine' and he asked for my father by first name. When I said he was unavailable and asked to take a message, he said he'd call back later and then asked if I was the Mrs. of the house. When I said no and again offered to take a message he said he'd try again some other time and hung up.
I answered and a man (unfamiliar to me) asked for me by my first name, I said that he (me) wasn't home right now, and asked to take a message, but the man said he would try back later and hung up. I have no debts, so I know it's not a debt collector, so it must be a telemarketer for a non-profit (since they can still call even though my number is on Do-Not-Call list).
