The heist app?

The heist is the number one game for free on the app store. When I got it, I kept getting these calls from a lady named sophia every time I played. So one time I couldn't decline the call so I just answered and it was like part of the the game. But then she said I want to meet face to face and then it went into face time. Is this a real person? The picture of her looked like an actual person but the call was automated. Is this just part of the game?
