Food Panda — refund not initiated

Address:

I placed an order with food panda on 19th sep 2018 and the order cancelled by them and they never refunded me the money. Food panda support has been harssing me since then. Its been almost a month now and they are not replying to emails or to any support from them. I have shared my paytm statement with them as no refund received. Still no help. Moreover i was promised cashback coupon of rs.50. Not received any such things.
