Disappointed & unsatisfactory

I got a travel insurance for a whole year as I was planning to travel around Australia. During the covid-19, I decided to remain in Australia as I have savings, work, and this country was dealing better than UK. I decided to help the farmers who lost their farms during bushfires. However my travel insurance didn't specify if I was covered doing "volunteer manual work". I decided to phone and check for advice. I have to say that I spent over a week trying to contact them. Few failed attempts of phone calls where I got hanged up. Then an email which was answered three days later with a totally different answer, and finally, after 5 more attempts of phone calls, I got someone to answer my question. " Due to covid-19 we are asking everybody to comeback so if you are not doing any effort to come back we won't cover you. However if you are trying to come back, we will". I believe this answer was extremely unprofessional and very disappointing. I did pay for a travel insurance for 365 days, and it is not up to the insurance company to finish my trip, as they are not even willing to return my money if I need to short my travel. Very disappointed. Awful customer service.
