Carnival Cruise Lines review: You changed my ship and entire room and guest relations

I went on the Carnival Venezia August 10th - 14th to Bermuda. I paid over $3,000 for a suite. When I originally made these arrangements I booked them on the Carnival Magic, You changed the ship on me. I booked a suite for the 7th floor middle of the boat dock side on the Magic. When I got to the ship I realized that you put me on the 14th flr in the front of the ship on the opposite side. I need to understand when you change a ship how come I wasn't put in the same area. I went down to guest relation they told me that they were full and didn't have anything available. She did tell me if I didn't like it I could leave the ship and go home. That phrase was uncalled for. Is this how you train your staff? I paid allot of money and got nothing I really asked for. I didn't get the ship I wanted. I didn't get the floor I wanted. I didn't get the side of the boat I wanted, I didn't get the middle of the ship I wanted and I DID'NT get the customer service from your guest relations that ANYONE deserves.
