"Hi,
We know refunds by Apple Customer Care are rare, but we need to handle them. We also know that in order to identify a cancellation we should check the cancellation_date field on the receipt. The question we have is how we know the amount which was refunded. For example, if a user subscribes to a monthly auto-renewable subscription, they have the subscription for 2 months. Then they complain to Apple and get a refund. How do we know if the entire amount (2 months) was refunded or only the last month?
Apple's documentation states "customer support can cancel the subscription and issue a full or partial refund". How do we know if it was a full or partial? They also say "treat a canceled transaction the same as if no purchase had ever been made", but if it was a partial refund this seems to not be true.
Thanks!
