Consider getting a call blocking device or phone.. You can google them and many are around $40.00 or so. If its a cell phone, some already have call blocking, if not, there are free apps on the web that will work for some. You can google this. If you have a smart phone, there is a free app called call control. Iphones appear to have apps also. Another one is called Mr. Number.

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

For text messages: forwarding any text message spam you get to the short code  “7726,” which spells “spam” on most phones, to alert your network operator to the abuse. ATT won't accept 7726 But they will accept BLOCK and return a message that the web site is blocked. forward the texts to 7726 or BLOCK, depending on your phone carrier.

Ignored the call, one scumbag among many

Robo-call, about item listed. Craiglist listing prompted this call. I hung up. Called again once so far. Reporting to do not call.

asking to help me with my "property" i do not own a home and have removed myself from their caller list. Multiple calls a day, different numbers, can't ever talk to a person.

"Unknown Name" and "Illinois" were on CID along with the 312#. Female ROBOT stating that "... banks have committed massive fraud ... $25B ..[reference to] legal representation .. some people have gotten their homes free and clear [presumably due to the robot's program]... Press 4 .."

Pressed 4, but no one ever picked up call. I've heard this message before.
