A separate app on my iPhone said this was a Telemarketer, so I did not answer. My caller ID showed an Unknown number with no message left. Therefore, that = telemarketers and or scammers. Most of these are "robo calls with spoofed numbers," so reporting them does no good. NEVER give or verify personal or financial information to ANYONE who makes an unsolicited call to you!!! I "block" these numbers if they keep calling.
I have hundreds of blocked callers and I got on the no call list but I keep getting dozens of calls from all over the country. How do ya stop this crap???
