Could be a scam. I got a mised call since it's a local number and it happened I was waiting for a call from the local post office. I called back the number but once it's connected,  it said "the survey now is done. If I want my number removed from it,  now press blah bla blah... I didn't do any survey and not sure if I press any button that may get my personal info so I hung up the phone.
