KFC India — refund not received despite many follow ups

I had placed an order with kfc via kfc app and made an online payment of rs. 800 (Approx). Order reference number in kfc app:[protected]. This order was placed to korum mall in thane which was far from my location due to which they discontinued the order in the app. They informed me that the refund process will take around 10-15 days. They have also informed me that my cheque number is 7867.

Today it's been almost a month i still haven't received my refund. On calling up call centre they tell me to speak to korum mall kfc and when i call up kfc korum mall they instruct me to speak to call centre. I've spoken to them quite a few times still haven't received my refund after so many follow ups.

Really disappointed with this poor customer service.
