This is a 'spoofed' number. Just ignore. Telemarketers are a pain in the [***], but they don't rank up there with what else is going on in our country. If you have seniors in your family, clue them in as to how to deal with this. They are most likely to get scammed.
Received a call from 323-621-5291 at 2:45 PM on 6/30/15. Caller ID showed as "Alarm Co." I answered and was some guy trying to "give" away for free a wireless security system and "upgrade the landline for free". Has all the earmarks of a scam. I kept saying I wasn't interested and he talked right over me. Not sure if it was a real person or a robo recorded call. I hung up.
All it took was one trip to LA and a car rental company to share my information with all the scum that calls me now from the state of California. Great job Hertz
