I am running out of "blocking" space... I get on average 15-20 scam calls/day on my land line and cell phone.... This has reach an unprecedented level of insanity.... Nobody at Federal level is paying any attention to it.
Try not answering unknown calls-they only continue to call because you continue to answer. Also do not call them back-by doing that you are probably getting more calls.
Be preemptive and aggressive in your blocking. Review where you have family, friends and business associates. Then I would go about reviewing where most your scam calls come from (NY, Wash. DC, big cities...etc). Depending on your blocker, I would start blocking entire area codes, why piddle around with single numbers. Also block toll free area codes if you do not need them. This method may not work for every one-but think about it. Review your blocker instructions and be creative-think outside of the box.
