Terrible Service and Late Delivery

Ordered a personlised gift from NetFlorist on 9 February, for delivery the 11th. I went into the website yesterday just to see that the order is now only being processed. I spent 18 minutes on the phone just to hear that Valentines deliveries now takes priority and the gift will only be delivered on the 16th. They advised that they take full responsibility, however no offering of a gesture of goodwill. The least they could have done is just deliver a bunch of flowers in the meantime if the order is still being processed. Now I have the expense of having to buy another gift (After spending almost R500 on NetFlorist already - including delivery) as I can't go to the party today without anything.
