[Resolved]  Indigo Airlines — flight miss

I missed my flight due to changing of gate number without informing me. I was waiting more than two hours for my flight in the gate number that as printed in my boarding pass. But at the same time the flight was departed from another gate number. They given me wrongly entered boarding pass that cause me lose of my valuble money and time.
This was happened when i was traveling from dubai to kannur airport with a connection through hyderabad. When i reaches hyderabad, i have got the boarding pass of flight # 6e7225 from hyderabad kannur airport with gate #108. So i waited at that gate more than two hours. I was also showed and asked to a staff working at that gate about the flight didn't arrived just 10 minutes before of departure time. She said to wait there. After some times i feel something wrong and i asked another l staff about the flight and they said that is already departed form gate # 102. I complained about this problem to indigo's staffs at boarding counters they said that they can't do anything.
I lost my valuable money and time because of their mindlessness. They have the duty to bring a person who took boarding pass and waiting for the journey.
