Cannot delete existing CF name servers. CF is my registrar
Followed all the steps, but there is nowhere to delete existing nameservers. (CF is my registrar)
DNS records
Two different sets of cloudflare nameservers is a very good indicator you are logged into the wrong account. Check the domain has nameservers here, DNS Propagation Checker - Global DNS Testing Tool. If the two you see on whatsmydns are not the two you see shown on this page, https://dash.cloudflare.com/?to=/:account/:zone/dns then you are most certainly in the wrong account.
The only way you’ll be able to regain access is by having access to the email address of the other account. I’d start with this link, if you don’t know the email. Do that and then check any other email accounts for an email on gaining access. This link may help, but it only work when logged out, if you don’t know the email: https://dash.cloudflare.com/forgot-emai
If you are unable to recover access to the account that holds the active domain, can you create an Account ticket and share your ticket number here? You can open an Account ticket here, https://dash.cloudflare.com/?to=/:account/support
