No longer have Adobe Echosign and when customers send documents to sign, I cant sign it.

My company used to have a subscription for Adobe Echosign and had it linked with Okta for SSO. We no longer have a subscription and we had all our user accounts turned into individual accounts. When customers send my users docuemnts to sign through Echosign, they are having issues logging in. They get the error:

"Sorry, you can't access Adobe Sign (EchoSign) because you are not assigned this app in Okta.
If you're wondering why this is happening, please contact your administrator." 

When i try to go to the admin console, there is no way for me to remove this Okta integration. When I called Adobe Support, they once informed me that the users under my subscription were turned into Inactivate free account. Im not sure if its the integration thats stoppings the users to be able to log in and sign a document, if its because the users are inactive free accounts, or maybe even both.
