I received a call from the same telephone number. No message was left. I called the number back...adding the *67 prefix. Reached a generic sounding telemarketing greeting.

We got a call from this number today at 2:54 pm and didn't answer. The caller ID was LYNN MA. No voicemail message was left. When I called back (our number is hidden by default on outgoing calls), I heard this recording: "Hello. None of our representatives are available right now. If you received a call from this number, we should contact you within the next day. If you believe you received this call by error, press 5 to be added to our do not call list." Since we are on both the national and state do not call lists, the call was a violation of the law. Unfortunately such scammers don't obey the law. The number will be added to our call blocker. I highly recommend such a device to avoid these nuisances.

yet another scam artist,,,,,,,.........

Received a CALL from JOHN at the HOME SECURITY CENTER. He said "blah blah blah".
So I hung up on the CREEP.

MADISON (WITI) — Wisconsin residents are receiving robocalls promising free security systems for their homes. Unsolicited sales calls are illegal. These current calls do not appear to come from a legitimate alarm company and are likely fraudulent. Hang up if you receive a similar call.

The messages will tell you that you can receive a free security system simply for having a sign planted in your front yard. You are provided with two options during the call: you can press a key to reach an operator or another key to be removed from the company’s call list. As with any other scam robocall, simply hang up and do not press any keys. Hitting a key will let the caller know that your number is active and may lead to an increase in similar calls.

To add legitimacy to the message or to catch the call recipient off guard, the automated message may open with a reference to the FBI. For example, the message may state:

“Hello! The FBI estimates that there are three break-ins every minute and urges you to take steps to prevent this from happening to you…”

The FBI is in no way involved with this operation. Don’t fall for this scare tactic.
