I picked up, a robo-voice said "this is a call for Michael (last name), if we have called your number in error, please call us back at"............I hung up at this point. When I did try to call back, all the circuits were busy, why am I not surprised, I assume the number is from some sort of boiler room.
My son's name is Michael (nobody and I do mean nobody calls him that) to anyone who knows him he is simply "Mike" and he has not lived at my address for 11 months.
