These people are most likely spoofing 626 area code numbers, and by so doing targeting numbers in the 626 area code to perhaps lend legitimacy to their calls???
In this day and age, nothing would surprise me...
And the caller ID on my cell phone displayed Uknown Caller. I never answer calls that don't show who's calling. Anybody that I talk to on a regular basis is in my address book, and their name will be displayed if they call...
I'm going to stick my neck out and say this was probably a scam call of some kind...
I called back and recording said it was a solar company without identifying name of company, to press 1 to leave a message and to press 2 to remove from list. My phone is unlisted and also on the no called list. I have so far blocked 189 scams and telemarketers phone. This phone is blocked.
