Cancellation of some of my iTunes In-App purchase?

Hi,

I see you want to void some purchases you have made such as in-app purchases. These could be either subscriptions or purchases of services or consumables.

You can cancel a subscription, but you cannot "cancel" a purchase such as an in-app purchase. However, you can ask for a refund for purchases or subscriptions. Read this article for how to request a refund for apps or content that you bought from Apple - Request a refund for apps or content that you bought from Apple - Apple Support

Note that although you can request a refund, Apple starts from the position that all transactions are final and it does not have to grant all refund requests.

You can cancel your subscriptions by following the steps mentioned in this related article:

In case you purchased the In-App purchase directly from the developer, you might have to contact them again, to cancel it.
