calls all the time no message left

all I can say is wtf lol I dont want random people knowing where i live.

they kept calling so i called them back.  they answered with "hello" not a business name, then they said i was chosen for million dollar sweepstakes winner,  and do i still live at blah blah blah...i said i dont feel comfortable giving out personal info who are you again ? how did you get my number? she said " online surveys and credit cards in good standing." (i do not have any credit cards that are not prepaid.) "you dont have to give out your perosnal info i will remove you from the list goodbye."    anytime i tried to ask ANY questions she acted very nervous.

stop calling me !!!!!!!!!!!!!!!!!!!!!!!

Did not leave message and have been calling my cell phone for days, and several times a day.  They even call on weekends.  Really a pain.  I do not answer these calls.  Wish they would stop calling.  I wonder how they get our numbers?
