Pending Nameserver Update (since week)

I Moved my site from Cloudflare account to a new one from one week till now the site status is Pending Nameserver Update I had changed my name server to new account name server
but still read from old account (that delete the site)
then I removed the site from the new account and add it again Cloudflare itself get that add the correct name servers

I’ve seen that happen before. Everything looks correct at your end. Contact Support and they should be able to get this working:
Login to Cloudflare and then contact Cloudflare Support
