Not sure how they got my work number but it is annoying. Just a rambling voice mail about a home security system. No thanks, I have a legitimate one from ADT.
Called, didn't answer, caller left no message. Am reporting this spam call to the Federal Communications Commission (FCC) at http://www.fcc.gov/complaints .... just click on telemarketing and hit next, and follow through and it will get rid of this number calling you. I got rid of one two months ago by reporting it to the FCC, and the problem was resolved quickly.
They are offering to install a security system in my house for free and I'll never have to pay dime for even the service itself!! WTF how did these [***] get my number
