Holland America Line review: Cruise and associated problems

All of the guests in our party of 8 contracted covid while onboard the Oosterdam, we, my wife Elaine Wilders and myself Paul Wilders were unable to partake of many of the activities onboard and ashore excursions.
Including the celebration 50th wedding anniversary of our friends at the Pinnacle restaurant for which we had a voucher and the excursions to Ancient Olympia & the village 1st July 2024 and Dubrovnik 3rd July 2024.
We paid £6,858.00 for our voyage.
We in fact paid some money for both excursions $59.80 twice.
3 excursions and meetings did not attend plus we were isolating in our cabin 5112 for many days ill in bed.
We want to have a cash refund for these unused excursions and facilities, not a same year reissue of the vouchers, no use to us.
We were also charged 70 Dollars for our medical records.
Would you also please send this and a copy of our full account ,as your IT systems will not now let me view them.
If you are unable to deal, please pass my email onto Gus Antorcha as he would want to know.
Please confirm the action you are taking over this
