Consumer Redressal

Hello, My flight was scheduled on April 19th with Indigo (to & fro) Delhi- Hyderabad. It was cancelled due to the COVID-19 Pandemic and i reported the same to Indigo by writing them a email and a tweet to get my refund but they didn't replied. Then for a month i kept writing them emails and tweets but they didn't even replied to any single of them. On July 30th, i wrote my last tweet to Indigo stating that i'll be taking a legal approach and will file a consumer complaint against them to get my money back if they don't give it because i am entitled to my refund. In response of my tweet, they replied that, " a full refund is applicable only if the booking is made between 25th March - April 14th for travel during 25th March- 03rd May". Now as per the cancellation policy of Indigo which they quoted above, My flight falls in the ambit of their criteria and i am entitled to full refund as my flight was booked on April 3rd and scheduled for travel on April 19th. So,I request you to interfere and instruct the airline to credit my money back to my account and i don't want it in form of credit shell because i am not a frequent traveler. So, a credit shell will be absolutely of no use to me. Expecting your kind support and revert as soon as possible.
