I read on this animuson's answer:
However, we do use Freshdesk, which has a separate portal with ticket viewing capabilities. We don't explicitly support this, which is why the login options are hidden in the portal, but if you can manage to get yourself logged in using the same email address you used to contact us, you can view your correspondence for the past year there (we delete tickets out of Freshdesk after they've been closed for a year). Last I checked, only the Google option allowed you to login to the portal without being a support agent - but I haven't checked in a while.
This is great to have access to tickets somewhere, but why are Freshdesk tickets deleted after they've been closed for a year? That'd be convenient to store them forever or at least a few years for archival purposes.
