Hello Proof of Concept,
Thanks for your question.
I will generally recommend you create a billing request for this as Keyvaults can only get charged in these circurmstances:
In general, when an object (a key vault or a key or a secret) is in deleted state, there are only two operations possible: 'purge' and 'recover'. All the other operations will fail. Therefore, even though the object exists, no operations can be performed and hence no usage will occur, so no bill. However there are following exceptions:
- 'purge' and 'recover' actions will count towards normal key vault operations and will be billed.
- If the object is an HSM-key, the 'HSM Protected key' charge per key version per month charge will apply if a key version has been used in last 30 days. After that, since the object is in deleted state no operations can be performed against it, so no charge will apply.

If the above doesn't apply here, you can create a billing ticket, here: https://azure.microsoft.com/en-us/support/create-ticket. This is completely free
