On Friday, I made one last effort to correct my situation. I replied to the SR response I had received, and, unbelievably (as I thought the request had been closed), I received a response:
"After further review, we have confirmed you are entitled to the $200 and an extra $50 per person shipboard credit. Please note we have forwarded an email to the ship.
On behalf of MSC Cruises, please accept our sincere apologies for any inconvenience."
The extra $50/pp would be VC Booking.
I didn't check until today, but the money (in €) is in my account.
