Cosmos DB account disappeared after moving subscription between tenants

Question

Yesterday we created an empty free-tier Cosmos DB account in a resource group. A few minutes later we moved the associated subscription to another tenant. Apparently, the resource group was automatically moved to the new tenant, including the resources, with the exception of the Cosmos DB. The Cosmos DB account cannot be found anymore, neither in the old nor in the new tenant. That's not really a problem since it didn't contain any data yet. The problem is that Azure refuses to create another free-tier Cosmos DB account, with the following error message:

{
  "code": "DeploymentFailed",
  "message": "At least one resource deployment operation failed. Please list deployment operations for details. Please see https://aka.ms/DeployOperations for usage details.",
  "details": [
    {
      "code": "BadRequest",
      "message": "Free tier has already been applied to another Azure Cosmos DB account in this subscription. To apply free tier to this account, you can select another subscription for this account or delete the existing free tier account. You can have up to one free tier account per subscription.\r\nActivityId: 7547c6a9-d7b7-4cd9-8168-49ddabf8d637, Microsoft.Azure.Documents.Common/2.11.0"
    }
  ]
}

How can we delete the (non)-existing invisible free tier account?

@Moritz Y. Becker We are sorry that you are having a less than ideal experience.
Unfortunately, we cannot troubleshoot this issue remotely.
Please reach out to Azure support so that an engineer can work with you and help you delete the account.
