robot call?

They called me (real person) and told me they wanted me to take some samples. but they didnt tell me what those samples were so i told them no.

Called but ignored

a gal said i had taken some survey and was entitled to a $100 gift card and a $50 prize.  i asked what info i'd have to provide in order to receive these items.  she was evasive so i told her she didnt answer the ? so i asked again and she said i asked a very good question so she was turning me over to someone who could asnwer it.  i hung up.

I didn't answer and like everyone say when I called back it says number not in service.  The problem is I have relatives in PA with the same area code.  They never leave a message so I will ignor. Can put on refject because don't have that on phone.
