[Resolved]  Indigo Airlines — no response over emails

I tried reaching indigo 3-4 times regarding my concerns. Each time the executive informed me to email, and on emails there has been no response.
I had booked a flight from dimapur to surat and had purchased indigo promise and also insurance.
Since more than a week i am emailing and calling them regarding how do i get the claim for both, but there is no response from indigo's end.
Also, i need certain documents which i need to submit to the insurance company which i need to procure from indigo.
