Carnival Cruise Lines review: Booked dining time

I booked my reservation Jan 2023, my husband died 25 Oct 2022. He loved cruising with you. This trip is meant to be a memorial to celebrate his life. 20 people are going from all over the USA. Last week I tried to get our rooms linked so we could arrange to sit together for dinner. We all had 600 PM reservations. Last night when the last person called to get her room linked she said your associate said none of the rooms had confirmed dining times and kept urging her to take the open dining of 530-8 PM. She told me she said no she couldn't do that without talking to everyone. Sheila Johnson and I check our bookings this morning and find the times have been changed. After 2 phone calls this morning I'm told that even though it was your associates mistake we'll have to be put on a wait list but don't worry we'll know something by 3 days before the cruise. I was married 44 years I don't know if you can understand the level of my grief but anticipating this trip was giving me a little joy. Now I have to agonize possibly for 3 months hoping things "will work out". How is this acceptable to your company.
