Holland America Cruise Line Holland America Cruise Line targets disabled in wheelchair for harassment keep losing the wheelchair. Seattle Washington

Holland America Cruise Line targets disabled in wheelchair for harassment.  They continuouly losing our wheelchair on offshore excursions, then deny a substitute chair insisting on charging rental, lure us to the opposite direction of dining room telling us "there is no dinner for you because you are late from the offshore excursion", when it is the cruise ship's fault bringing us late, then call the security to detain us lying that we attack them!  We are disabled in wheelchair and female-senior-citizen paying expensive fair for 17-day cruise, in the middle of the ocean and several hundred of Holland America Cruise staffs, How do we attack them??

My son is diagnosed with "Tardive Dyskinesia and dystonia" and in pain without his wheelchair.  The Holland America Cruise Line's staffs could clearly see him in pain but do not care and continue with multiple harassments.  We ask for refund but the cruise line responds that it is justified of their actions because my son's wheelchair is located and returned within 2 1/2 hours!
