Air India Express — Refund Not credited even after 6 months

My Air India express Ticket (QKHZCN) from TRV to DXB was cancelled from company side. I went to Air India express Sharjah office regarding the refund status. They informed me that the refund of Rupees ~7905 is processed on 10 th of October 2020. Till now the refund is not credited to my Card. I have contacted the customer care 7-8 times already.

I have been addressing this issue for the last 5 Months. Made many calls and mails. No response. Every time I am getting the same response that My amount will be refunded within 7 working days. It has been 5 long months.
