Can’t sign in to feedback site

Basically, I can’t sign in on the Feedback and Suggestions site. When I click the login button, it allows me to put my info in, but then it takes me back to the site and I’m still not signed in. This has been an issue for a while now. I was able to do it fine and I had multiple posts, comments, and followed posts. I’d get the email notifications if there was a new comment. One day I realized I hadn’t received one in a while. I went to the site and it was all gone. My posts and comments just weren’t there anymore. It’s like the account got deleted but it didn’t. I can sign in to my Microsoft account elsewhere, I’ve tried different browsers and devices, and I’ve even tried to contact someone in the “Help Center” twice but never got anywhere. I see there are other posts on this issue. One has some steps to fix this but they seem outdated because they frankly just don’t make sense. Please, any help would be much appreciated. It would be nice if the account could be reopened with all the same comments, posts, and follows still in tact but if not, I’d take just the account being reopened.
