Samsung - refusal to assist - head office international has no control on their branches

my son bought me a flip phone and when it got here the screen was not working and the clip came loose, we reported it but because he bought it on a MSC crouse ship when they docket in south africa they now say that the phone was bought abroud and they will not fix it under warantee, rediculous. so what if the boat was in the middle of the see. who do we go to then, why have a shop or sell your phones on cruise lines if you are going to expect clients to go back and spend thousands to get back on the same ship to fix it. rediculous. it is still a samsung brand and samsung should be held accountable no matter where this phone is bought. almost a year later and no assistance.
