They called my very private cell phone number at 1:15 PM PDT on 30 May 2017. The caller ID said "Athol, MA". I did not answer. They did not leave a message. My phone numbers are on the Do Not Call list.

I have a feeling that the phone call spammers are starting to use random phone numbers that belong to ordinary people who don't realize it. When I check phone numbers here for the last week or two, most of the time I find an "empty" entry for that number. Perhaps people are getting lazy about making entries, but I don't think that's it.

Never call them back, not even from a blocked phone. They have ways to unmask your phone number even when it is blocked.

Called my cell number at 1:30 pm from Athol, MA.  Did not answer and they did not leave a message.

Called at 9:00PM!  Caller ID was "Athol."  No message left.  Presumed telemarketer.

From Athol, MA 4:19 PM  PDT
Called & hung up when I answered. I knew it was probably spam but I wanted to yell at someone to take my name off their damn list.  What good is "Do Not Call"? Blocked the number.
