Passenger wrongfully locked up in Cabin

This is belated because I have tried to contact them directly but emails returned undelivered.<br> My wife and I embarked Southampton on QM2 May 2010 to cruise western Med. Everything was fine until the night before we arrived in Naples. I am a medical doctor and know myself. We went to the sickbay and asked for one Immodium tablet as a possible prophylactic measure. I was completely healthy but their nurse and duty doctor over reacted and reported me sick. I was duly locked up in my cabin for 24 hours. We missed our excursion to the Isle of Capri. I was fed unpalatable food and threatened that if I leave my cabin I would be put ashore at the next port to make my own way home. There was nothing wrong with me. I think Cunard should compensate for such mistreatment.
