I have the same called they called 4 times in the same day 3 times back to back I have 6 blocked calls from these people on my log. They just don't get it.
He had my wife's first name and wanted to talk with her, when I asked who is calling: "Never mind, I'll just call back later". I hope he calls back, as I will prompt my wife to give him an ear full, especially if he's selling something.
