Worst company to deal with absolutely no communication

Cruise holiday package with Costa cruises from Dubai to Savona Italy for 13 March 2020 to 5 April 2020. In September 2019 we booked a cruise/flight and hotel stay with Imagine cruising. When it became known in Fefruary 2020 that the coronavirus was a matter of concern in Italy I sent an email to Imagine requesting that we be refunded. They responded several days later that this was not possible. On 1March I once again sent an email to them advising them that the coronavirus was a threat in the cities that we we due to visit in Italy. As we received no response to email we made two phone calls and did not receive a favourable response. They eventually responded to the email on 10 March indicating that the cruise was still going ahead and that should I wish to cancel then I would lose all money paid. To avoid a no show policy we boarded flights to Dubai on 12 March and checked in at the Tulip hotel on 13 March. That night at 23:15 we received a letter from Imagine cruising advising that the cruise which was to depart the 14 March was cancelled by Costa cruises. The Sunday 15 March we were put on flights back to South Africa. It is now over 2 weeks and we have had absolutely no correspondence or communication from either Costa or Imagine cruising. I notice the response that imagine cruising give their customers who log complaints on hellopeter is that the customer must contact their customer service team and that they will explain everything. How disgusting by imagine cruising, they have the customer details, why don't they get in touch with their customers
