Basically was the same thing, get a call and WOW! I won $1000 .... I told the chick I had already heard about scams like that and all she said was "...oh!" n I hung up! .... It was just a one time call tho, if I get a call from this number again Im gna tell them I will report them as a "scam company" online.
I've been getting blocked and unknown calls as well, I answe but get nothing, I just call my phone company and my phn line will simply reject those calls :)
This number has been calling me everyday, twice a day for about a week now. My husband answered it and they asked for me saying they were a publishing company. My husband handed the phone to me and they hung up. We tried to call them back and got rings but no answer.
