We have recently updated our Support ticket form with some naming changes. For Cloud Support:
(1) Terraform Cloud has been renamed to HCP Terraform. To submit a ticket for Terraform Cloud, select "I am a Cloud User" > HCP Terraform; (2) HCP Vault has been renamed to HCP Vault Dedicated; and (3) Billing, Account & User Management and HashiCorp Virtual Networks are now under HCP Platform.
