How do I cancel Apple subscriptions and get a refund?

This is a user to user forum. You are not speaking to Apple here. You need to cancel your subscriptions yourself; we fellow users cannot do it for you.

Subscriptions and Billing - Official Apple Support

Note that cancelling your subscriptions will not automatically entitle you to any refund for subscription periods for which you have already paid.

First, be sure to ⇢ cancel a subscription. ⇣

Then click ▶︎ Request a Refund.

According to Apple:

If your refund is approved, the funds are applied to the same payment method that you used to buy the item.

Here's how long it takes for a refund to appear on your account or statement:

Store credit—It might take up to 48 hours to see the refund in your Apple Account balance.

Mobile phone billing—It might take up to 60 days for the statement to show the refund. Processing time might be affected by your carrier. You can contact your carrier for an update.

Credit and debit cards, Apple Pay, Apple Cash, and all other payment methods—It might take up to 30 days for the statement to show the refund. If you don't see the refund after 30 days, contact your financial institution.

Note—Once a decision has been made on your refund request, you will get a follow up email from Apple.

Click ▶︎ Check Refund Status.

Final Note:

I have written a detailed user-tip on this subject that goes into greater detail.

Good luck! 👋🏼😉
