OP spoke to a cabin steward who knew of the cabin problems and indicated they'd told supervisors yet it was still assigned at embarkation. It's reasonable to assume the cabin wouldn't have become so uninhabitable in only a few minutes unless it was a massive water leak from above which surely would've drawn the interest of superiors and ship's officers.

The insistence on villainizing the OP is unfortunate as while I didn't agree with them seeking more compensation beyond what was given and said as much upthread I have tried given them the benefit of the doubt that the version of events was more or less accurate though it's become obvious you feel otherwise.
