MSC LOST PROPERTY - DISAPPOINTMENT

We were on a cruise on the MSC Sinfonia from 26 December 2017 to 6 January 2018 (Durban - Mauritius). When we returned we noticed that my daughter's watch was missing - she thought that she might have forgotten it in the cabin when we disembarked but I did inspect the entire cabin before I left it for the last time. I wrote a e-mail to the lost property department of MSC on the 13th of January 2018 to enquire. I sent further e-mails on the 5th of February and again on the 16th of February to ask for a reply. I also phoned MSC but could not be assisted. They only told me that should they not find the watch, the insurance should pay out for the loss. They further informed me that the lost property department will send me an e-mail after their investigation to inform me of what action will be taken. To date I am still waiting for such e-mail. All I received to date were only reference numbers. This watch also had sentimental value to my daughter as I bought it as a present for her in Croatia. I am very disappointed in MSC that they do not even attempt to respond to my e-mails. They were quick to accept my money for the trip, but very slow in responding to lost items.
