Look suspicious so I did not answer- I am on the DO NOT CALL LIST so how do they bypass this?

Called around 130pm; Left no Message.  Did a google search on the number, came up as a night club called Rumor in Philly (which I've never been too).  
I am guessing the number is wrong for that?  Although the color idea just identified it as Pennyslvania.
Either way, called my cell phone number, which only close friends, family, workplace have access too.

*Caller ID, not Color Idea.....

Have received 10 phone calls from this number. I have answered how I always answer. With my name, because I use this cell for business. I either get a hang up immediately or silence. Getting "fed up"!

got a call from this number and a woman with a thick accent who assured me this she was not selling anything.  She said it was just a quick survey about home safety.  Foolish me was trying to be nice and answered her questions.  She began telling me that I could be entered to win a home security system and I told her I was not interested.  She told me to "shut up" - I was stunned!  I asked her - "did you just tell me to shut up"?  She said yes, but... I cut her off, told her that was rude and I was ending the call and hung up.
Caller ID just said "Pennsylvania" - I sure won't pick that up again!!!
