If there's disclosure order towards your case that it will take sometime for them to investigate the issue then maybe yes. So I guess you need to follow up then to know what's the latest update about your case since somehow 7 months of waiting is so long.
Maybe try to know what cause for more delays since for sure they have their own reason why this incident is happening. For now reach to then and try to be nice asking about the latest update on your case to know if they are still working on it or they just forgot your issue.
