you can waste your time with filing useless reports or buy a call blocker....search for phone blocker..the one i have,has 1500 number blocking capacity..dont buy phones or blockers with 50 or 60 number capacity..you will run out of numbers in a couple of months.
These criminals will not stop calling..so do yourself a favor and buy a blocker.
I have already blocked 610-922-8911, -8912, 8913, and 8914 through Time Warner... (so I don't even get one-ring.) Now I have blocked this one on the phone... with only 30 numbers that can be blocked at each place, there are not enough slots to zap all of the numbers this sewer sludge uses without letting through some of the other slime that I also need to block.
