Waiting for payment means payment has not yet been accepted for fulfilment. A paid order can progress through work in progress, delivery and completion. Read any message from G2U for the next step or missing delivery details.
Payment status and delivery status are related but separate. For a pending crypto transaction, see payment still pending. Ask in the order chat if a status is unclear.
