AWS Managed AD services

Hello, We are using AWS Managed Microsoft AD services , but recently the domain controllers(which are managed by AWS) has the issue, we can't resolve them because we don't have access to it and it seems without paying for premium support we can't ask AWS to fix the issue of their service. Please let us know what options do we have , because we are getting trust issues,RPC errors, we can't create or manage users, computer .
