This number keeps calling and calling my phone and leaving no voice mail.

Calls everyday, no voice mail. I got the not in service message when I tried calling back. Annoying.

What ever made you think scammers and thieves would honor that list?  And those real ones that do, get fined and socked pretty good, you need to file reports..  But don't think its going to stop those scams,extortionist and thieves! Charity's and Political calls are also exempt..   but most will remove you if asked!
You can also sign up for a political no call:

But stopping the phoney phone calls from the scammers and thieves is on you! There's lots of stuff you can do if you bother to read up here..

The do not call list does nothing to prevent calls every day

bothersome repeated phone calls from this number 954-368-5455

This number has been calling me daily, sometimes twice, for weeks now on my cell.  No voicemail, but I did pick up and it seems to be a company selling insurance.  I can I make it stop?

Keeps calling, I don't answer, no voicemails left.

Florida broker for health and life insurance trying to give u the best deal on ins.

Has call numerous times; no voicemail left.  Really aggravating

Received a call from 9543685455 and when I called them back to found out what was the call all about, a message reported that such number was no longer in service (??), so it seems to be a made up originating number (you can do this these days with the use of soft - IP based - telephone PBX's or witches)

Called no vm. It seems to be an Insurance Company selling policies.

This number keeps calling me, no one talks, no VM

Just I got call from this number on my cell phone for the first time ever. I didn't answer it &  no voicemail  left.   If this should repeat,  then  I'll block it.
