I never pick up, haven't answered in 10 years because of this calls. This poor fellow, Dennis Duval, has just had his number spoofed. I once called a guy and yelled at him only to learn he had no idea what I was talking about when I realized he'd been spoofed. Receiving a plethora of calls, yet again, thru California spoofed number.
I blocked and called back, message states " The person you are calling does not take unidentifed calls, you call is blocked, to unblock your number....." This may be a legit caller who opted not to leave a message.
