Dear @Paruchuri_Prathap,
Since you are dissatisfied with the response from both Indigo customer care and AirSewa, you can escalate your complaint further.
You can contact the Directorate General of Civil Aviation (DGCA) through its grievance redressal portal at Sugam DGCA.
Alternatively, you may also file a complaint with the National Consumer Helpline (NCH) at consumerhelpline.gov.in or take legal action through a consumer court.
If still need help, reply to us.
