How do I unpublish a site without access to it?

[tpg]

My organization has built a new website and we need to have an old, outdated, no longer properly maintained weebly site unpublished so that Google stops indexing it. No one at our organization has access to be able to do this on our own. Can you help? The site is: https://greenfieldfumc.weebly.com/

Hi @tpg. It looks like the owner of the account was able to successfully login a few hours ago. I suggest reaching out to them to see if they can unpublish the site. You will also want to submit a request to Google to remove outdated content once they unpublish or delete the site. https://www.google.com/webmasters/tools/removals?pli=1

Thank you. I will see if we can figure out who that might be.
