KFC India — Did not receive my refund

I ordered from KFC app on 9th Aug 8.30 pm and the order automatically got assigned to my nearest KFC i.e KFC Avani Mall, Kolkata. But after a couple of minutes the manager called me up and said that he is cancelling my order as my house is too far (the app only assigned it to them). Now it has been more than two weeks but the amount that got deducted from my KFC gift card did not come back. Even after calling the manager numerous times my issue was not solved and it keeps on getting delayed. My KFC gift card expiration date is coming closer and I am not getting my refund back. And in the app it shows "cash on delivery", I dont know why. I beg you to please look into this, it has been a pathetic experience with KFC.
