So:
1) you haven’t actually purchased, only tried a free plugin
2) you claim that it didn’t work for you without providing any screens
3) you didn’t open any support thread/ticket to allow us check/fix those bugs
4) you mention that those are ‘miner bugs’ (I assume it’s a typo and you meant ‘minor’
5) “when you click on the term it doesn’t redirect to the glossary index page” – that’s not even a bug, as it doesn’t suppose to happen
6) “When you change the glossary slug term it doesn’t change until you uninstall and reinstall the plugin.” – there’s much simpler method we mention often – going to WordPress -> Permalinks and “Save Settings”
And yet based on that you try to exaggerate that it will ‘destroy’ website and discourage not only from using the free version, but also from buying – so in our opinion it’s not only fake review but slandering.
