LittleApp — they are not refunding

Address:	110016
Website:	littleapp.in

I placed an order on little app, i paid via paytm bhip upi. But my order was not confirmed. I had been begging them for a refund from past 3-4 days, no one is responding. I also contacted the customer support via their app and separately via email.. They are not responding. They are not even replying to the emails. It does not take 4 days to refund someone's money or atleast admit mistake and reply

I need a quick resolution. I want them to be punished for insensitive and irresponsible careless behaviour towards their customers
