Amazon music unlimited subscription

At this point, you basically have a couple of choices:

• Request a refund for the subscription that you got through the Apple App Store. Ref: Request a refund for apps or content that you bought from Apple - Apple Support
• Contact Apple Support directly as I mentioned in my first reply to you. Ref: Get Support

What exactly is not working? Are you using the Amazon Music app, or accessing their content via a web browser on your iPhone?

Are you a current Amazon Prime member? Are you trying out their unlimited service via a trial, or have already subscribed via their app?

Note that although Amazon provides this subscription service via the Apple App Store, it still is their service. Any subscription issues would need to be taken up with them. Also note, that we are not Apple Support here. Instead, we are just fellow Apple-product users trying to help others where we can. As such, there is nothing we can do to assist you with this. If you want to get with Apple directly, then just select the "Support" link on the lower left-hand side of this forum's web page.
