Received a call today from these guys. They don't realize I live in a 95 yr old house with water baseboard heat, NO DUCTS AT ALL!!!! Like them to try and clean them out. Maybe they could give me an estimate. :)
Gee, if you don't fall for their scam the first few hundred times they call, they must figure that you shall fall for it within the next few hundred calls?!??!? They spoof numbers, change their name ID tag, and generally operate like the usual scammer. No way to stop them from calling.
The woman who called claimed to be offering some sort of air duct cleaning service. I said, "if you are a criminal, hang up" --- she told me that she was not a criminal. So she is not only a criminal but also a liar, not that it matters, since she will never be caught.
