Air India — waiting for refund

Address:	New Delhi, Delhi, 110037
Website:	Air India

I am shantanu gupta. I had travelled from ai 173 on aug 13 from delhi to sfo.
My pnr no was z49jr and e-ticket no was 098-[protected]. I had booked paid seat no 17k. But the seat was having the problem and was not reclining. I had complained about the problem to the crew members and they had given me a seat at back and told me that you will get a refund for your seat. But even after 11 days of my travel, i haven't even got a single email of apology from your side.
Kindly reply me when you guys will be giving me my refund.
