As a self-described long time business leader, why have you not thought to follow-up with Celebrity? If I had not received a response to my email after a couple of weeks I would be sending an email to every Celebrity email address I could find to inquire of the status of my claim. Phone calls might be an even better method.
If you had travel insurance, a claim would have been settled by now. It appears you travel without insurance.
Threats to cancel future bookings or contact nationally published reporters likely will have no effect. A cancellation will give Celebrity an opportunity to resell your booking at a higher fare and cause you a lot of work rescheduling all that goes along with cruise travel.
If you have no inclination to follow-up with Celebrity, use this as a learning experience and move on with your life.
