Who to escalate to when Bing Webmaster Support fails?

So, like many others I'm discovering, my website disappeared from Bing on July 5th, 2022.  

My site was ranked #1 for it's particular subject matter and is still ranked #1 on Google.

I've contacted Bing Webmaster Support on July 6th and was told they couldn't see any issues but that the ticket was being escalated to Engineering.

It's been over a week with no response on the ticket since the last one.

I've e-mailed since the escalation but have been ignored completely.

Where do we go from here?  My traffic has fell off a cliff in regards to Bing.  It has been over 13 days now that my site has been completely deindexed.

My site in question is at https://ephinea.pioneer2.net/  as well as it's forum at https://www.pioneer2.net/community/

Please let me know whom I should contact and where as this is ridiculous.

Thank you.
