My parents were travelling from Bombay in Indigo flight and they had a camera . They gave their luggage in checkin and when they received the luggage after landing on delhi airport, camera was stolen. we were not expecting such service from your airlines. How can someone take our valuable item from luggage. This never happened in other airlines. Kindly consider the issue on urgent basis or i will file a complaint in customer court.
