[Resolved]  Indigo Airlines — delayed flight and staff attitude

On the 14th of july i was due to travel jaipur to dehli with airindigo, and then delhi to london with another airline. We boarded our airindigo flight (Ref whv8ra), and then were told it was going to be leaving 20 minutes late. I asked the air hostess what time we would arrive and she said it would be the same time. I said that didn't make sense. Then after half an hour i was worried and asked again. The air hostess said it would only be half an hour late by then. The air hostess showed no concern or empathy for the fact i might miss my flight, instead assured my i would make the connection. We ended up leaving approximately an hour late. Based on the information the air hosetess gave i did not cancel my connecting flight. The flight ended up being 1 hour and 20 minutes late to arrive which made me miss my connection. I had to pay over usd800 to book a new flight because i missed check in and the second airline classed me as a no show.
Luckily i had travel insurance, however i have not been able to complete a claim because air indigo has not sent me through an email with written evidence that the flight was delayed, the actual arrival time and the reason. I have called the call centre twice but no one has helped me. I am very unhappy with the service.
