Swiggy — food isn't delivered and money is deducted

After receiving the order and money has been paid, swiggy made me to wait for 30 mins and later i get to know that the restaurant is closed wtf it really sucks, the service is not at all good and upon this the money is deducted and not refunded, it says money has been initiated for refund but i didn’t get any money, this case happened with me thrice. I need to lodge complain on this for my losses. Worst experience ever
