called first time i didn't answer, they called back again with the next hour and i answered and said hello couple times but no one responded. they just hung up on the other end of the line:S whoever it is STOP IT!

They should have to say who they really are.  I went through the survey (dumb I know) but I could really see the slant the call was taking and I am pretty sure I know who it might be!

Just called here.  Picked up because I thought it might have been a friend's cell #.  I said "hello" twice & no answer received.  Sounded like someone hung up so I did too.  Will keep an eye out for this number in the future.  If they were legitimate they wouldn't hang up when you answer the phone.

I also received the same call this evening. As I was out, the answering machine picked up the call. No message was left.

Answered this call, no one responded.  Hung up because I knew it was retarded.
