Non Delivery of paid for products

Ordered and paid for flowers on Wednesday, with the promise of delivery to Worcester hospital on the same day. Paid immediately, person never got the flowers I sent. Today(Thursday), I phoned in and was told that the florist in Worcester only opens on the 11th of January. Was it not the responsibility of Netflorist to inform me of this before I checked out and paid? Today the person is not at Worcester hospital anymore. I was told I'm getting a refund, but the whole meaning of giving this person the flowers on Wednesday is of no use anymore.
