Does anyone here have an email address (or web form address) for Cloudflare support?

I'm asking because increasingly often, Cloudflare-protected sites give me an endless loop:

Performing security verification This website uses a security service to protect against malicious bots. This page is displayed while the website verifies you are not a bot.

Verifying ...

After a few seconds, a "Privacy" and "Help" link are shown next to the word "Verifying". Then they all get replaced with a spinner icon, and the cycle starts again.

The help link goes to this page, which says:

You may encounter a challenge loop where the challenge keeps reappearing without being solved. This is in very specific cases where we detect strong bot signals. If you are a legitimate human, you can follow the troubleshooting guide below to resolve the issue or submit a feedback report.

Well, I am a human - even if my legitimacy is debatable.

The troubleshooting guide takes me here, which says:

Turnstile Failed Despite Passing All Checks All diagnostics passed, but Turnstile still couldn't complete successfully. This is unusual and may indicate an edge case. ... Since the local diagnostics did not find a clear cause, this may require investigation by Cloudflare.

• Copy your Session ID from the top of this page
• Click "Copy Full Results" in Technical Details below
• Share both with Cloudflare support

But it gives no contact details for Cloudflare support.

A web search turned up this page, but it only lists contact methods available for Cloudflare customers. I am not a customer.

Hence my question at the top of this post.
