Disappointing camera

I bought an X-T10 about six years ago. Suddenly it stopped working and I took it through to the Sandton branch to be fixed. They came back to me and told me it couldn't be fixed. No explanation. Does this mean that the longevity of Fujifilm cameras is 6 years? Unfortunately I have 2 interchangeable lenses which I love, so I would be forced to buy another Fujifilm camera. Based on the experience above I am loathe to do so.
