Please free my domain from your Cloudflare service

I started having 404 errors 8 days ago while proxying through Cloudflare, I moved to my own VPS because of that, but 404 errors are still appearing

Cloudflare support told me this:

Me: I started having 404 problems after I moved my services from to the personal VPS-server.

Cloudflare: Could you please write to all your previous SaaS provider and ask them to remove the custom hostname for the two hostnames? 
As we mentioned before, your zone is configured as a custom hostname under their account, causing the conflict.

Can you please free my domains?
Where I can mention domains in questions not in public?

i @yatxone - I’ll follow up with you on this via DM!
