Air India — absolutely no response regarding my refund status

Address:

Flat No. P-3, Vidyasagar Niketan, Block-EA, Sector-I, Salt Lake, Kolkata, West Bengal, 700064

Already sent 4 reminders on the subject to [protected]@airindia.com, but no response yet.

I have cancelled the bookings (Pnr y1mx6) per flight no. Ai 21 (Ccu~del) scheduled on 07th nov 2019 & ai 20 (Del~ccu) on 12th nov 2019. It was confirmed to me by some customer service lady of air india on phone about a week ago, but no email confirmation has been given to me even till date. Further, the necessary refund status is also unknown to me.

Regret it's not the right way of dealing with ai customers. I am very dissatisfied!!
