Very dissapointed

I ordered flowers online on the 15 May 2019 and received confirmation of my order which cost R80 for delivery alone. On the 16 May 2019, a confirmation email was sent stating that my order was delivered at 9:32am. On flowing up with the person the order was for, they had not received it. When I called netflorist, they confirmed that the florist had not received my order. How do I get confirmation of an order being delivered at a exact time of the order was not made to begin with? Had I not followed up, I would not have known that an order of R580 was just never made or delivered.
