Who called from 4162479291

It's the same duct cleaner with a new number. Now blocked!

Thanks to all correspondents for the information.
I blocked as soon as I read "duct"  My ducts are already all in a row, thank you.

I tell them my ducts have flown south for the winter

They called twice in one hour 2 minutes apart. I do not answer when I do not know the number. I am blocking.

Nobody answered when I picked up the phone. Eventually disconnected.  Likely telemarketers.
