Bing Webmaster Support Team - Not Responding to any support tickets

It is crazy as this seems to be happening to a lot of legitimate websites. A few years ago, I got mad at Google and specifically switched to using Bing search engine only. Since then, the platform has pretty much become unusable with search terms rarely reaching relevant content. The news portion of Bing is hilariously bad. Any of the financial news sites have been written by scripts with errors that you can point out. We need an alternative like Bing, but it is quickly becoming clear that Bing can't fulfill that role. I use Edge mostly but never use Bing anymore because it isn't reliable. I am also in the same boat as you trying to find out why a site was deindexed with no email or notification. Support ticket hasn't been responded to yet, but your post gives me little hope that I'll ever get a response. I've tried adding new meta descriptions and reuploading the XML authentication file for the site. Will return if anything changes. Good luck!
