Foodpanda - Refund not received

I placed an order (z*ye-ke**) with FoodPanda on **-Sep-**** and made payment of Rs. ** via Paytm wallet. The delivery address was in Baner, Pune. The order was cancelled by FoodPanda citing excessive response. I received an SMS indicating the refund has been initiated and I will receive it within * hrs for wallet payments. Later I received an email indicating the refund would be processed within *-** working days. I patiently waited for ** working days but refund was not received. I sent an email to their Customer Care and they responded with a standard response saying there was a technical glitch in the refund process and they have escalated the matter and refund would be processed in another *-** working days. I again waited for further ** working days. Now I know it's just a gimmick to delay the refund process so that the customer gets frustrated and gives up the chase for refund. I contacted them over chat through their app. They kept me on chat for over an hour. During this process they kept on changing the operators, with each one asking me to repeat the same set of questions and providing the same set of responses. They are not ready to provide any transaction details of the refund process which clearly indicates they haven't processed any refund. Over the same chat multiple operators gave me multiple dates for processing of refund which is totally fake and fraudulent response. They are incompetent to handle customer queries and say anything irresponsibly. I have shared all the information with them including my Paytm wallet statement but beyond the initial automated response, they do not respond to any mails.
This is a large scale online fraud being run by FoodPanda. If I search online, I see numerous customers being duped in similar fashion. Customers are enticed by fancy offers, their orders are not fulfilled and then money not refunded.
This company should be blacklisted and banned from operating and a hefty penalty should be slapped on it so that it closes down and cannot loot people further.
