Sorry to hear you are stuck in this loop trying to get your subscription issue resolved. You normally should be able to pay your bill if your subscription is disabled. To do so you can Resolve past due balance in the Azure portal or by using Pay Now.
The link provided in the error also allows you to create a support request. If that doesn't resolve your issue you can try contacting our Azure Sales team via chat or phone to assist.
Hope you are able to get your issues resolved. Let me know if I can assist further.
