How can I get OVH to delete unused accounts when services are blocking it?

I'd send one clear erasure request for each account and ask support to identify every item still blocking deletion. Include the ticket references, the errors from the deletion page, and which services you cannot remove yourself. Ask them to confirm whether the vRack cancellation or project removal is still pending and when it should finish.

If ordinary support keeps looping, ask for the request to be escalated to the team handling privacy requests. Check OVH's privacy policy for its data protection officer's contact details and copy them in if available.

If GDPR applies, the usual deadline to respond to an erasure request is one month. That is a response deadline, not an unconditional promise that every record must be deleted within that time. Erasure has exceptions, and the period can sometimes be extended for complex or numerous requests, with an explanation.

Keep the original request and the replies. If the deadline passes without an adequate response, you can complain to the relevant data protection authority and provide that correspondence.

Account closure and removing the services blocking it may be separate steps. Ask for a specific status on each Public Cloud project and vRack, including whether cancellation has been submitted or is merely awaiting another team. A pending cancellation could explain the automated rejection, but support should be able to clarify what is still in progress.

Try to keep this focused on the account deletion problem rather than whether OVH is good or bad overall. The infrastructure and pricing may work well for some customers, while support and account management can still be frustrating. Neither settles what is blocking these particular accounts.
