Apollo Pharmacy — Apollo 24|7 pharmacy order

I had placed an order for 2 Rapid antigen test kits in Apollo 24|7 App yesterday (3rd June 2022) at 02:18 PM and paid in advance Rs 445 . The order was supposed to be delivered on the same day by 04:30 PM.
Today is 4th June 2022. I have not received an update even after emailing the customer care. I want to cancel this order and get full refund as this is not delivered as promised.
