got call from same number with inaudible talk, and dishes rattling in the background amongst people talking. then they hung up

I asked them how they got my number, and they somehow had my address. Then she talked about some sweetstakes and then hung up. Kinda worries me that they have my info...but they wanted to confirm it (I think)

310-539-1783 Caller ID reads "CA READING SERV" (CA Reading Service).

Just got a call from 310-539-1783.  Missed it - no message left.  Called it back, and had a lot of background hubbub, and a woman who said "What is your name?"  I asked why.  She said, "Just tell me and I'll take you off the list."  I said who are you.  She said 'Sweeptakes - just tell me your name and I'll take you off."  I said off what?  She says, "Is it Brenda or Mary or (whatever) - which are you?" I asked her again why - and she again said its a sweepstakes and if you tell me your name I'll take you off.'  I said I didn't think so... and hung up.  1, I don't give my name to people who don't already know it, and 2, why would I want to be taken *off* a sweepstakes anyway - seems like a person would rather be put on...if anything.  At any rate, I'm fairly sure she was just trying to get a name to match up with a cell number, and I'd like to know why.  No text sent - all voice.

Received a call and the person on the phone stated that I had won $25,000 for a sweepstakes, I told her I was leary of the call, and she asked for my address.  When I asked why, she hung up.  When I called the number back it was busy.
