My cell phone is on DNC list for 3 yrs but still telemarketers are able to get thru.  This # has called quite a few times.  I never answer & it continues to ring.  Does DNC really work?

The Do Not Call List is a list.  Telemarketers are required by law to buy a copy of the list and not call anyone on the list.  Legitimate telemarketers - the time share sales pests and photography studio pests who used to call me - follow the law.  I haven't gotten a call from them in more than 10 years.

For a scammer the Do Not Call List law is just one more law to break.  Many of the callers are located outside the US, out of reach of US law enforcement.

What To Do When You Get an Illegal Robocall; http://www.ftc.gov/bcp/edu/microsites/robocalls
1.    Hang Up. Do not press 1 or any other numbers to get off the list and NEVER call them back
2.    Consider blocking the number or on a cell phone add it to a contact list and assign NO ring tone
3.    Report it at http://www.fcc.gov/complaints
4.    Report it at https://www.ftccomplaintassistant.gov
5.    People should continually file complaints with their Attorney Generals office
6.     Report any criminal activity to the FBI here:    https://tips.fbi.gov

This is an all out attack from these scum suckers! EVERYONE should be reporting them everywhere that they can. Since this is an obvious attempt at identity theft and is interstate, the FBI should be forced to get involved.

Called cellphone, I did not answer, no message.  Very disconcerting since I have a dying relative in Detroit and thought it might be an emergency.

I have had 4 calls today. why report these calls nothing is ever done to put a stop to them?
