MSC Cruise agents failing customers

To whom it may concern.

I booked a cruise for 01/03/2019 and I was told it is supposed to be fully paid by 16/12/2018. I however can not payment online of about R 6000 as it's not displayed under my booking . I called MSC on two separate occasions, their agent said I would have to settle this via EFT, I then requested for the banking details to be either sms'ed to me or emailed. I have been waiting on this information for the past 2 weeks.

Please assist!
