Telemarketer.  Doesn't seem to help to be on National Do Not Call List.  Calls like this come through anyway!

Call and hang up w/o message

No message left, called back only to be told the number is disconnected or no longer in service.

My phone system allows me to block calls, and that number just got plonked right in there

just called me as I was walking in the door I did not have time to answer. They didn't leave a message, so I immediately called right back and a recording said the number has been disconnected or no longer in use

Anyone who gets these calls, immediately report every call to the FTC.  It's illegal and they need to be stopped!

Same thing just happened to me.  I did press '2' for no more calls and will have to wait and see.
Hopefully the pressing of '2' won't actually subject us to some other scam or charges on a
phone bill, for instance.

I get calls from this number 3 or 4 times a day, both cell and land line. Automated message starts out "Do Not Hang Up this is not a sales call." goes on about a "free" secuity system.   Right!    I don't want what ever it is that they are hawking, doubt if it is free. Hanging up didn't work then I tried to press  #2 to register that I do not calls about this, but am still getting calls, then I tried press #1 to talk to someone and got a full voice mail?  No one to talk to.
I am registered on the National Do Not Call List for both phones, but it made no difference. How can I get these calls to stop?

Received call from this number 12/6 at 6:28 p.m.  Said they were home security experts and wanted to give me a free system. I am on the DO NOT CALL LIST which doesn't seem to be working anymore. I blocked the numbers they call from but my phone service only allows for 12 blocked numbers and mine is full with these calls so I can't block anymore. I've turned them into the FTC and heard nothing.  Where are our legislatures that could go after these people.  They like to send through bills, then write one for this problem.  I'm sick of telemarketers !!!!!

This f**** call me and I am on the National DO NOT CALL list.  They say they are giving away a free home security system.  I hit one to talk to someone and when I said I was upset with the call they hung up.  I called back and got the "This number does not exist" message.

I will report this to the nation do not call people.

Voice message indicates that they are experts in home security system

I got one this morning, I was on another call. They did not leave a message.
