Indigo Airlines — Missed connecting flight

Address:	06033
Website:	Indigo

My daughter and I booked a flight with your airline, flight no. 6E32, on March 11, 16 which scheduled to depart from Kathmandu at 14:45 and arrived to Delhi at 16:05. During the flight, the captain announced due to bad weather, we had to fly to Jaipur, we landed at Jaipur airport for some time and flew back to Delhi around 19:40.
We had a connecting flight from Delhi to Abu Dhabi with Etihad which scheduled to leave Delhi at 20:50. After we deplaned and went through customs and immigration, we missed the flight and we had to rebook two tickets which costs us $1607.54 USD. (803.77 each)
It is not our fault we missed our original flight and we should not be punished by having to pay for the tickets.
I would like IndiGo to reimburse us $1607.54 USD.
Your attention to this matter is greatly appreciated.
