Air India — boarding denied

Respected sir,
Today me and my family was about to travel from chennai (Maa) to trivandrum (Trv) for ai 976 with departure time at 6.15 pm. We alreday did web check-in.
As it is a domestic travel, we reached to domestic gate by 5.15 pm. I am pregnant and i was accompanied with my husband and mother in law. Airport authorities in domestic terminals misdirected us to different departure points and finally one person told that the flight will be from international terminal. We were very much confused and started walking towards international terminal. And then we got help airport shuttle cab from apollo services and reached international terminal by exactly 5.40.
We went to the check in counter of air india and it was mentioned closed. Person at the counter was just telling that counter is closed and we finished checkin early. We were very much confused and worried. He told us to talk to a officer
Of the air india services who was sitting in next counter. He also told the same. We requested whether he can do something and he was not all listening to our excuses. We were not intimated by air india about the terminal or early checkin completion though we did web checkin. Then they tried and asked us to keep the baggage for weight check and i really dont know what happened. One more officer came and asked the other officer to quickly do the tagging. Suddenly they stopped the procedure and told again that not possible. We requested it is ok even if we get the baggage delayed at trivandrum. They wasted almost 15 min in this discussion and still there was 15 more minutes for flight departure. They directed us to the air india office over there and again there they told the same thing. We asked for re-schedule of the tickets and they calculated the fare as around 18 k for the next day. We are so frustrated and sad by the behavior of the airport authorities, because of the conversations and time waste we had to cancel the tickets as we cannot afford 18 k for re-scheduling.
If anyone in the authority was considerate about the situation as the main delay happened because of terminal change which was not known to us and unwanted conversations.
Kindly consider this as my humble request to refund the ticket money of three o[censored]s.

Regards
Priya parvathy padmakumar
