Indigo Airlines — Indigo airlines

I booked flight for 5th march 2016 from bangalore to nagpur (6e 435) i paid for extra luggage also they issued us boarding pass inspite of all these formalities got completed i was unable to board only because of ground duty staff. There was no announcements on airport and i was stuck up in the security check, they gave preference for the passengers of delhi flight but not me as both flights were on same time. As soon as i reached to boarding gate lady told me that flight already departed and one of my friend who was in flight he called me to come quickly as flight is ready to fly but she didn't allow me to go and if flight was departed already then how my luggage will come back within 5minutes through air? I think they did it purposely. I booked same flight for next day and they charge for that also. It was worst experience both financially as well as mentally stressful as being a girl i am alone in new city and paid extra to live there for whole day but indigo airlines does't care about what kind of torture they gave to their passengers they only meant for money.In future will never opt for this airlines. For any action taken on this issue i provided here my pnr no. S33qxr but doesn't expect much from such a ridiculous airlines. Refund of money is like a dream for me but atleast indigo customer care authority will read this and will give better facilities to its upcoming passengers that's all i want.
