maybe she dialled her family but no one picked up the phone or
line was busy at that point of time. Knowing she had little time to
make a call, she randomly pressed no. to ask for help (even though
it would sound too unbelievable to the receiver of the call).
Second thing, she doesn't rmb what our police hotline is. Or if she
knows, the kidnapper may warn her that if she called the police,
her life might be in grave danger. Just saying that this is a
possibility.
