worst experience ever - flights delayed- gates locked - no refund - no plan b

We had booked cruise for the 29th of Jan 2024 on the msc Splendida to Moz. Saved money for months for it. Firstly, when we booked, the booking said that the ship departs at 6, so I booked flights to have us arrive in Durban at 4 so we can be early. the Friday prior to us leaving I get an eticket that says that the gates close at four, so I had to reschedule our flights and pay an extra 600 for this change. come Monday, the day of our Cruise. our Flight was scheduled for 14;20, only flight that was avail that i could reschedule to, which will arrive in Durban at 15h20 and it is a 30min drive to the port so we would have been 10min early before the gates closed. There was a storm on Monday and our flight was delayed and we only left JHB at 15h05 and arrived in Durban at 16h05 and the port at 16h35. before we left JHB and while in the plain waiting I was in contact with MSC letting them know that we will be late because of the flight delay and they said there is nothing they can do, the gates close at 4. but we can go to the port and see what they say. We had to take an Uber, my husband and myself for R400 to the port only arrive there with 20 other clients waiting outside who were on the same flight as me and there was a rude indian guy that came to attend to us and told us we are late and there is nothing they can do about it, so we must vacate the premises and sad part is we could see the ship right in front of us, but they didn't care and refused to let us in. We had to again pay R400 for the uber to take us back to the airport and because we had booked our flights for the Friday when we return. we had to move it to Monday and pay another R1000 for that. I then phoned MSc on Tuesday and there was no care, no empathy. just them saying that i lost everything and they will only give R3000 back which will be refunded in 30 - 60 days and I am considered a no - show. How is this possible? I was there! there are no options, nothing! we just lost all our hard-earned money like that!!! it's now Friday and i still have not received the refund documents to complete. I feel if they have it their way, they would not want to give you anything back. Worst experience ever!!! I would not recommend anybody to do this. it's a ****!!!!
