What does being single have to do with siding? Do not answer calls you do not know, never call them back and get a call blocker and use it. I also might let you local police department know the line of questioning this person used on you-it sounds VERY SUSPECT.
I received a call from Mark at American Siding and Windows on my private cell phone. I asked him how he got my number and he said that he pulled it from the Polk County Assessors web page. I told him that was impossible and he said that is how he obtained my number. He said, "well regardless, can I help you with a new roof, windows or siding?" sales call...
The guy said he was with Extreme Makeover and I was 1 of 3 homes to get done in my neighborhood. I asked how he got my number. He mumbled something about public record. I said my number is on the do not call registry. He said "your cell phone?" I said yes. He said thank you and hung up.
Said he was American Siding and Windows and was with a home makeover show. Asked for my address, if I was single, and if I was usually home during the day or not.
