How do I recover documents I created in Confluence if I stopped using Confluence for several months

[Checalomexico]

Months ago, I drafted several documents, writing documentation about parts of my personal project, to back up my ideas. Months later (today), I need to use those documents, but when I logged into Confluence, they all seem to have been deleted. It must be because I haven't made any payments or used the tool for several months, and perhaps they deleted those files.

My question is: if I pay for a subscription, is it possible for them to help me recover them?

I hope you can help me soon; I'm a little sad and I don't want to lose those documents.
