Very disappointing with no-show delivery

I placed order for delivery 14th February to a business address. On the profile it says that if order is placed before 12h00, it will be delivered by close of business and that some priorities will be given to business deliveries. Order was confirmed for delivery same day. However, a call was received from the delivery person at 17h22 - way after business hours. Arrangements were made to deliver flowers at receivers residence. Nothing happen. Receiver called delivery guy at 18h24 - he confirmed that he will deliver by 19h30. But he did not. Waited up to 20h30, then proceeded to continue with our other plans and salvage whatever time remained of the night. Since it was pointless to receive the items any other day, I emailed Netflorist that night to cancel the order. They haven't responded to the email as yet.
