Grant IAM Users Permissions to File Support Cases
By default, IAM users on an account can't access services and functions unless the root account user explicitly grants them access. For instructions on granting permissions for particular IAM users to file support cases, see Accessing AWS Support.
Also, be sure that the IAM user has permissions to view and access any services they might want to contact AWS Support about. For instructions on updating an existing IAM policy, see
Even with administrator permissions, IAM users cannot perform all actions on an account. AWS Support might be limited in what they can discuss with IAM users, but can speak with the root account user about all details related to an account and its resources.
