Air Arabia Cancellation Refund

I had a ticket with Air Arabia on the Istanbul–Kathmandu route under reservation code 63DG3U. I cancelled this ticket on 04.10 and although the flights now appear as cancelled, I still have not received the refund. The total amount I am expecting to be refunded is 300 EUR, but no payment has been made back to my account so far and I have not received any clear information about the status or timing of the refund. I kindly request that my refund of 300 EUR for the cancelled reservation 63DG3U be urgently processed and the amount be transferred to my original payment method as soon as possible, or that I am provided with a clear written explanation if there is any deduction or issue.
