Swiggy — refund not yet credited to bank

I have ordered 60 puffs for rs 2241 and due to delay of more than a hour. I have cancelled my order and message was received stating refund shall be initiated. Yet I didn't receive anything even been a week since the order was cancelled. Now that I have to check with my bank and this will take a long time thus got fed up with these things. It makes me feel like always opt for cash on delivery so no worries. When a delivery gets cancelled. I am really worried about this thing.
