Re-activate blocked service automatically on payment

When a customer pays via the portal - using a credit card e.g. Netcash/Stripe and their services were blocked, if the payment is successful, it would be most helpful to have the system automatically then re-activate the service.
At the moment we have to wait for the notification that the payment was made, then for the admin to go and process it and unblock - but as the transaction is already there, it is logical to go-ahead and process the status change on the customer.
