The Walt Disney World Florist can help you.
Don't expect miracles though....
Back in Dec I ordered a basket for my wife. It was our 10yr anniversary.
Get into the room and no basket. Called the florist 5 mins from closing and they hadnt even made it yet. We left and came back around midnight. Not there. Left the next day to go to parks came back and there was a basket, but it wasnt what I had ordered.
I called when I got back home and they did things right for me. They apologized profusely and refunded my money. I was happy with this. All I was looking for was a little credit, not a full refund.
Me personally Id be hesitant to use them again.
