HappyEasyGo — Money Credited to them successfully but no tickets provided

I booked a flight from Ranchi to Kolkata on 9th April 2023 for a flight 6E7235 on 13th April 2023 at 19:55 departure and an amount of 4155/- was credited to their account.

But they didn't issue any ticket nor did I get any sms confirmation. Miraculously the customer care person picked my call once and said the funds will be returned which never happened. Now, none of the customer care service numbers are working for help/support. I filed a complaint to my bank who also confirmed today that the money has been successfully credited to their account. The bank statement clearly states that the amount is successfully credited to them. I wrote several emails to them but they never bothered to reply.
