Same thing happened to me today, 8/8/2014. Kim called but I do not think she was a real person, just a computer recording. I told "it" we have a no "sign on lawn policy" and hung up.
Got a call tonight on my cell phone from 571-364-0138. It says SRVC CALL I just got a new phone and would normally not answer, but seeing Service Call come up made me think someone was calling about my phone service. It was "Kim" trying to sell or "give" me a free security system. I said DO NOT CALL THIS NUMBER AGAIN and she just kept talking, so apparently it is an automated voice. I blocked the number in my Mr. Number app.
I was receiving calls from Comcast and saw this. On Caller ID, list as SRVC CALL, thinking it was a service call. Crap, I wished I knew this was a scam!! I happened to leave a message to that number!!
