Air India — cancellation of flight

Address:

403515

We had booked a flight air india cochin-bangalore - goa on 27th november. The flight was at 1.40 pm. We arrived the airport at 10.40 to be informed by a message that the flight would be delayed and would depart at 3.40 pm. Subsequently, when i went to check on the same i overheard them saying they were cancelling the flight as the flight had only 11 passengers but we were told the standard statement 'for technical reasons'.
Subsequently we were put on a jet airways flight 1.50pm but were re routed to mumbai. The flight landed at 3.55 pm at the international airport and air india refused to forward the baggage directly and insisted that we pick our baggage in mumbai and check in at air india mumbai.
Meanwhile the mumbai goa flight was at 4.50 pm. Our baggage from jet airways came only at 4.25 pm and my husband &myself both senior citizens were running with suitcases onto several floors to check in at the air india counter. I had asked for help in mumbai (From cochin) as i knew there situation would be chaotic but no one came. They gave me a number and said that person would help us out. But that number was of the help desk and he said he couldn't leave his desk.
After picking our baggage and climbing yet another 3 floors we arrived at the air india check in counter. I went directly to the ai manager as we had crossed the check in time but she was making and receiving calls from one phone to the other until i asked to stop phoning and listen to me. Fortunately, some officers around helped us and even sent someone to accompany us to the aircraft. We entered the aircraft at 4.40 pm for a flight leaving at 4.50 pm. Besides being senior citizens my husband is also a heart patient..
How will air india compensate us?
