Air India Express — Loss of my hand luggage

Hi, I was a passenger in the Air India express(IX 474) on 27th Feb 2015 from Bahrain to cochin.After getting on the flight, one of the cabin crew took my hand bag from me, for the reason for finding space even if I told him want to keep it with me. He assured me it will be safe with him.When i asked about my hand bag the cabin crew told its been moved to the luggage and i have to just collect it from luggage collection area of Cochin airport. As my valuables were in baggage i was worried for moving my bag to luggage's. I did't found my bag in the Cochin baggage collection area.I filed a complain about my lost hand bag with the tag proof. They told they will find the bag and will contact me ASAP. Even after I called several times, they didn't help me finding it. Now I have to return and I need the certificates that I have kept in the missing handbag .So Pls help me find my hand bag.And please contact me on [protected], [protected]. alias.[protected]@gmail.com, [protected]@yahoo.com Regards, Beeva.C.Varghese
