In my state there were telemarketers doing the same thing regarding home security systems & were targeting the elderly. They already had general info on the people they called & when they found out which homes already had security systems & which ones didn't, they'd rob/burglarize the ones lacking security. :-(
I didnt answer either and they didn't leave a message. Verizon here. I always make it a rule to not answer if they are not on my contact list. If they don't leave a message, as soon as I can, I Google the number and find just what I'm reading in all these posts. I'm thankful for sites like this allowing these blogs.
Received a call from this number today on my cell. Did not answer it and called back from my office phone. Got a vm message telling me i can add my number to their do not call list. Sounds like their phishing for real phone numbers to sell later on.
