Received a call today.  I did not answer and no message was left.

two hang up calls in a row. no message

Called left no message

When this call came (only 2 times in a week) -  I answered it only the 2nd time-   they don't speak -  eventually they hung up, after I mentioned the "police are tapping my line".....   nothing more, nothing serious, just odd.  Until now, I never noticed there was a place to submit a report - but it's a good idea -  I often do searches just to see where the call came from,  after a caller gets annoying, but never before saw a place to report anything about spam calls.  And I notice in the past, most spam calls originate outside the USA.   Thanks for this service...

I keep getting calls from these people.  They ask for me and when I acknowledge they hang up.  I called back and finally got through but when I started to speak they hung up.  Who are they and why are they calling?????
