So i booked my spa service using this promo code and called in to see if i could change the date and time without canceling and to my suprise. Later on, i found out that the representative had cancelled it, and it's only a one-time use promo. Now im screwed and they said there nothing they can do about it and are saying its my fault. SO thanks for the great customer service Carnival, you really know how to take care of your customers!
