Its not the Policeman's responsibility to stop these type of calls, its the responsibility of the FTC,FCC and CFPB's.  And at that, thee is only so much those agency's can do as a majority of calls are spoofed numbers. The DNC isn't a call blocker and can not protect you from the illegal callers, extortion scammers, foreign country's and frauds. Criminals do not obey laws simply said.    They use spoofed numbers which make it hard to track them down.. it takes time to do this and many subpoenas for call records.

Do a search for call blocking devices & phones. They are a big help to stop the calls.

Report your callers here, not just to the DNC alone:

Same here.

Rang 2 x's ...  Don't answer unknown numbers.  Read the reports.  All the same.  What a bunch of losers!!!   Get a real job.  People are catching on to all the crap being dealt.

They hang up quickly so you will call...then they are off the hook for illegal telemarketing

It rang once and then hung up. No message left.
