Unable to create service bus under CSP subscription using PowerShell

Hi,

I have two types of Azure Subscription 1) CSP Subscription ( through re-seller)  2) Pay As You Go (Direct Subscription)

I am using following PowerShell command (using rm account) to provision Azure Service Bus

New-AzureRmResourceGroupDeployment -ResourceGroupName TestRG1  -TemplateUri

Using the above command ,we have successfully added a new service bus under Pay As You Go subscription.But when tried same way under CSP subscription ,we get the error following error 

New-AzureRmResourceGroupDeployment : - Error: Code=DisallowedProvider; Message=The operation is not 
permitted for namespace 'Microsoft.ServiceBus'" 



What is going wrong here? Is there any limitation under CSP subscription that there is no way to provision few services like service bus etc.

Since under CSP subscription, only ARM is available and no option for service bus management through classic portal ,so only option is to use PowerShell to provision services.

Thanks
