Input: What was meant to be the holiday of a lifetime turned into a nightmare for an Australian man when the formerly fit university lecturer was left stranded in a foreign hospital for five weeks after a severe stroke. John and Christine Rose were on a holiday in Slovenia in June last year, visiting their daughter Bernadette Smon, her husband, and their grandson, when the sprightly 70-year-old suffered an unexpected and significant stroke and was rushed to hospital in the capital Ljubljana. The couple had taken out the highest level of travel insurance with Allianz Global Assistance, and despite being assured on the day of her husband's stroke that the funding needed to bring him home would be quickly provided, Mrs Rose was left helplessly begging the insurer for five weeks before any action was taken.John and Christine Rose were on holiday in Slovenia in 2014Mr Rose suffered a severe stroke and was rushed to Ljubljana HospitalThe couple had taken out top-tier insurance with Allianz Global AssistanceMr Rose waited five weeks to received funding to fly him back to AustraliaCompany allegedly blamed 'world events' and 'time zones' saying process is 'complex'
