MSC CRUISE REFUND!

I've booked with MSC cruises for the past four years and they have never failed to deliver quality customer service until the year 2020. I was initially booked to cruise in the year 2019 Dec. It was however canceled/postponed due to the pandemic. I started calling and emailing MSC to cancel my trip and request refund for the deposit I made as I'm no longer interested because the dates keep changing. Msc either doesn't respond to my emails or they tend to come up with stories about how I'm forced to avail myself for the next sailing date. I've recently made contact again and they now claiming that I can't request refund because the ship is postponed to sail in Dec which only gives me two weeks notice of cancelation. My problem is that I tried canceling and requested a refund for the past two years and there seems to be new regulations each time clients requests a refund. I'm completely annoyed and disgusted with the way MSC has been conducting business since this pandemic.
