I have gotten repeated span calls from this number.  It said from Gardena, CA.

Called 8 times in one day no message, lot of calls for a home security scam lately, when I called the number back comes out as no longer in service

received several calls today,  Called back the number and a recorded female voice said it was a home security system.   To be put on the 'Do Not Call List dial 8

We'll see what happens

You might want to answer the call and see who it is.  One company doing this (VMS) has recently been cited by the FTC, so you might want to collect who is doing this and report them there.

Also, find out who is doing the monitoring, and include that in the report.  Especially if it's Monitronics.

Home security scammers, advertise them and you get free service alarm and installation, I don't believe this.
