Swiggy — haven't received refund

I have ordered on swiggy on oct 3 2019 and because the restaurant was closed the order was cancelled. But it showed that the restaurant was open. Anyways i have paid online for it through card and haven't recieved the money yet. I contacted customer care. They told me to contact bank and i did, bank told me that i haven't gotten any amount refunded. Swiggy is not helping me, i feel cheated
