Deleting an organization in private cloud

[#1]

I am trying to delete the organization using the documentation. But , I got a message like.

{
  "code" : "servers.binding.RemovePodsBeforeDelete",
  "message" : "There are pods associated with organization XXXXXX. Remove them before deleting",
  "contexts" : [ ]

So, later I tried to disassociate the pods. But the response I got is

{
  "contexts" : [ ]
}

and nothing is changing, Any ideas?
