They say they are calling from ADT.

Don't know who this is, and they won't say who they are.

diamond alarm co of ADT.  you can press "2" to leave a messaeg if you want to be on the Do Not Call list, but the message box is full

I just moved into a new rental unit and have been receiving numerous calls where no one seems to be on the line.  I called this number back and got a message saying it was Diamond Alarm Company of ADT.  I had the option to press 2 to have my number taken off their list but when I pressed 2, I got a recorded message.  I left a message but am not certain whether that will actually work.

I have received at least 3 calls per day from them the last several days.  I finally blocked the call.  I didn't have this problem when my number was unlisted.

I get this call every morning. No one seems to be on the line. It hangs up after about 15 seconds. I suspect it,s a computer phishing for FAX numbers.

They called and asked to speak with the home owner. I told them I don't own a home (we rent) and they said thank you and hung up.

ADT install free security items.
