Consumer Redressal

My Name is Albert. I booked a flight from Frankfurt to Kochi on 23rd of June last year. Unfortunately the flight got cancelled and i applied for a refund. After following up the refund a lot, i got the information that my refund is processed and amount is refunded on 30th december 2020. But until now the money has not reached my account. Iam attaching booking reference, my bank statements and related E-mails with this letter. I kindly request you to take necessary action. otherwise i will be forced to move legally.
