Got the call. Didn't answer, but they left a message. The message didn't identify the name of the company, but went into a long spiel about how good they were at cleaning windows, gutters, sidewalks, driveways, and everything under the roof. Left a number to call back 866-322-3838. At the end of the recorded message, it sounded like someone came on the line. They said hello? hello? then started tapping on the phone with a pencil or something. I looked up the 866 number here also, but nothing reported yet.
Just a little advice from a little ol' lady: It's best not to call any of the unfamiliar numbers back, but never give them your name and telephone number if by chance you do call. Just because the area code appears to be the same as yours, disregard that. These numbers are spoofed and aren't of any use in determining the origin of the call. Next time, ignore the call and try to block any future calls from that number. Incidentally, I just had a call from this number myself. I didn't answer it.
