MSC Cruise Bummer!!!!!!!!!!

I am so dissapointed with MSC. We were told our trip has been cancelled after we had made full payment and we were told we either loose our money/ get a voucher/ choose another date for our cruise. It’s even impossible to choose another date because leave days had already been secured at work! What annoys me the most is the fact that we kept asking if there wouldn’t be any changes about the cruise and we got re assurance that things are still the same and our trip will happen as planned. What are we suppose to do with vouchers!!!!! We want our full refund!!!!
