Food Panda — not received refund yet

I had placed an order on 19th september. My order number was n5gj-2gwj, t7ga-9s6b. I still haven't received the refunds. I had mailed them several times and i got standard response of 7-10 working days and always mentioning they had a technical issue at their end. Till date i haven't received any refunds.

I noticed in this chain that many people are facing this issue. It will be really good if they can be notified and told what they are doing.
