You can request refunds only for subscription resources, such as subscription Elastic Compute Service (ECS) instances and resource plans. If you no longer use a subscription resource, you can unsubscribe from the resource and request a refund for the resource. Then, Alibaba Cloud collects the resource based on the rules for unsubscribing from resources and refunds you the fees for the resource. If you no longer use a pay-as-you-go resource, you cannot request a refund for the resource but you can release or delete the resource in the Alibaba Cloud Management Console. After you release or delete the resource, billing for the resource stops.
You can request refunds for Alibaba Cloud resources in the following scenarios: you unsubscribe from in-use resources, cancel resource renewal orders that have not taken effect, automatically unsubscribe from resources that fail to be created or updated, downgrade resource configurations, change the billing method of resources from subscription to pay-as-you-go, and return in-kind products.
