Sorry for the issue you’re encountering.
I do not see an account associated with that email address.
The domain has a long history of using Cloudflare

The current nameservers DNS Propagation Checker - Global DNS Testing Tool are
chip.ns.cloudflare.com
lana.ns.cloudflare.com
Those are not the two assigned to your account. I suspect what happened is the following:
-
You added the domain to the account you are using here and purchased a pro plan for $240 in that account, you can see the invoice here, https://dash.cloudflare.com/?to=/:account/billing
-
The nameservers associated with the account you are using here are,
magnolia.ns.cloudflare.com
titan.ns.cloudflare.com
- But those nameservers are not the nameservers currently in use.
-
The domain was added to the account you are using here 16/4 and removed on 21/4
-
You purchased the pro plan in an account where the domain has never been and is not active.
I think we’re going to need to have Support help you on a case. If you already have a case, Support will respond to you on that case.
If you don’t have a case, you’ll need to follow these directions here, Billing, Plans & Subscription Questions. The Community cannot assist with Billing, Account, Trust & Safety, nor Registrar issues, you need a case with Support.
You’ll also want to figure out what account holds the active domain as it may be easier to contact your domain registrar OVH and have them change the nameservers from the current two to just the two assigned to the account you are using here. In that case, you’d still need to re-purchase the plan as a credit would have been issued for the cancelation and will be used after the first period payment. As it’s an annual plan, I suspect that means you’d pay for another year and the second year the credit would be applied. In that case, you may be better to pay month to month in order to have the credit consumed. But again, Support would need to assist on a Billing ticket.
To identify the account that holds the active domain this link may help, but it will only work if you are logged out of your Cloudflare account, https://dash.cloudflare.com/forgot-email
After you try that link, check every email that may be associated with the domain. It is not the one you are using here and is not the one you shared on your post. Please share your case number once you have it as I’d like to add myself to it to track progress.
