Figured I would try the route of Jira because the contact option only gives you an automated response. So it never has been resolved.

But for the longest I haven't been able to change the name of my Minecraft account due to the counter on the site being bugged and counting negative days. I have a screenshot attached of what I see

So it never allows for a profile change. And if a tested on another account it works and shows the correct timer and the text box populates to change.
