SEAVIEW Room - without a view

As per my booking, I paid for and was promised a Superior SEAVIEW room. You can hardly hear the ocean nevermind seeing it. Before our departure I was in contact with Imagine Cruising stating the fact that they must make 100% sure I will get what I paid for! They assured me that all is in order. Now that I'm here... it's nothing what they promised. They can send a e-mail but thats apparently all they CAN do!
