Who can help? Bing bots refuse to crawl the content.

Bing support has been ignoring me for the past 9 months, repeatedly sending the same response:

"The submitted URL is known to Bing but has some issues preventing indexing. We recommend following the Bing Webmaster guidelines to increase your chances of indexing."

I discovered the issue and fixed it, but even after a long time, the site still hasn't been indexed.

I have tried all the methods multiple times to speed up indexing, but it didn’t work.

Bing is connected, but Bing bots refuse to crawl the content.
