Im complaining about payment and refund

I m sristee chanda, from guwahati, i want to submit a complaint
Payment made by me today is successful, but after payment it hasnt redirected to zomoto. So order failed abruptly. But refund was not provided. When i contact the bank, they said transaction was successful to merchant, for any information contact the merchant. But zomoto isnt responding. Bank statment says that transfer to atom technologies. But if transaction hasnt reached zomato, why the transaction is not rolled back.
