Once an order is placed, it becomes unmodifiable. The only feasible option is to cancel, a possibility reserved for purchases in their initial processing stages.
As the preparation phase advances, cancellation becomes unviable. Once a tracking number is allocated, the most convenient procedure is to reject the package during the carrier's delivery attempt. This will prompt the parcel return, expediting the refund process.
For transactions still in their early stages, and eligible for cancellation, customers will receive an email confirming the cancellation and refund.
