I didn't answer, they didn't leave message. For a long time I was blocking all these scammer calls til the list was quite long. Even if blocked they'll use another number. If I don't recognize number I don't answer. Done!
Called twice on May 25, the second time at 9 pm, which is too late for any robocall to a residence on Eastern Daylight Time, but the Caller ID says California, so I guess they don't know/care which time zone they are calling. Good for the guy who picked up and answered no to everything. That's the latest scam,- to ask if you can hear them, and, if you say yes, they record that and then claim they have a record of you agreeing to something they are selling.
Called once at 7pm, then today at 9:43am, from some type of Back Brace company. He said "can you hear me ok?" I just hung up. I've heard of scammers asking that and the person on the line would naturally say "yes" and it gave them permission to do whatever they intended to do, if that makes sense.
