Got a call from this number , on my house phone. I answered and said inportant message from credit card .  a man got on line who spoke bad english like from middle east ,, Iran or somewhere,,, and said we see you have a credit card and we can lower your interest on your card. I said I don't have a credit card , don't believe in them,, he kept telling me about credit card lowering interest I said, you must be a computer,, I said mr computer hope you crash . I hung up.

I got a call from this number and didn't answer since I didn't recognize the number.

The FCC cannot do anything?  Didn't the feds just manage to break the iPhone encryption of the San Bernardino shooter without the agreement of Apple?  And they cannot prevent telemarketers from illicitly using the in-country phone numbers of Americans?  Or maybe they just do not want to badly enough.

Ben thanks for the clarification

There is a solution to, if not all of this, then most of it. But I can't tell you of it because if and when I do, this site won't post my message. Hint; run a search for 'unwanted call blocker'. It's a free service and it was the Winner of the FTC Robocall Challenge a few years ago.
