Who called from 6504496517

Called 5-27-2017, 8:56pm, 5 seconds, no sound, spammer

No message. Must not want to really talk to me. BLOCKED.

Total scam. Philippine boiler room with spoofed numbers. Call multiple times per day from multiple different numbers. Do not answer. Do not give them ANY information unless it's your figurative middle finger. BLOCKED.

I get multiple calls daily from variations of same number...650-449-65##...I can hear many operators talking in background. I've asked them repeatedly to stop. They threaten to CALL MORE and laugh. How do I block numbers that keep changing?!?!?

You block whole area codes, area codes and exchanges, or wild card numbers.  You do this by reading the documentation that came with your call blocker.
