Terrible, Terrible service from MSC cruises South Africa

We booked a cruise two years ago. Because of Covid (and I understand that) the cruise was cancelled. We had to apply for vouchers and book the cruise again for Feb 2022. When we booked during last year, MSC had the dates and days wrong, so the cruise was again cancelled and we again had to apply for vouchers to book for the correct days and date. With many issues going forth and back, MSC decided to change the ships from the Musica to the Orchestra. So once again we had to change. With all that happened, one of our guys in the group passed away due to Covid. What a mission, we had to apply for a voucher again to get a credit voucher. That credit voucher was suppose to be used for a new cabin booking. That was June/July 2021. They never issued the voucher and the cabin was cancelled. The new cabin was only booked last week Friday - 14 days before our cruise departs. This were only a few of the issues I had. Now because of the delay from MSC and the slow response and excuses every day, we have different embarkation times for the group booking after we were promised because they messed up, they will make sure we can embark as a group. Obviously because we have already booked flights and shuttles etc. Now all of a sudden, they refuse and have excuses that they cant change the embarkation time. It is one week before we depart and still I have issues, we still dont have cruise tickets, nothing.
