Air India — refund amount

Hi sir/madam

I had cancelled my online ticket booking with pnr no. Hhz4j (Ai)

Ticket no.[protected] on 17th nov 2019

I booked it online on airindia website using my debit card. I cancelled it due to a family emergency.

But still i have not received the refund amount it's been over two months now.

Please clarify the same!

I have also emailed at [protected]@airindia.in
