Account was closed. How to get my data?

I’m not sure how but my account seems to have been deleted. I tried to log in one day and was told I no longer had an account but I could create an account for $14 more per year than I have been paying for years. There was no messaging about this change that I have seen. What I couldn’t manage to do was back up my data. So my question is, who do I ask about getting my data, if it still exists? This forum is the closest Newsblur seems to have to direct support. So here I am, asking.
