Q: Bought accidentally applemusic. How can I cancel this ?

Hello j0j02122,

If you want to cancel your Apple Music subscription, turn off the auto-renewal option in your iTunes Account information settings:

Manage your Apple Music membership on your iPhone, iPad, iPod touch, Mac, or PC

On your iPhone, iPad, or iPod touch

1. In the Music app, tap your profile icon in the upper-left corner.
2. Tap View Apple ID. You might be asked to sign in.
3. Under Subscriptions, tap Manage. If you have more than one subscription, tap Your Membership (Apple Music Membership) to see your membership options.
4. Under Renewal Options, turn off Automatic Renewal.
   
   
5. Tap Done to return to your Account screen, and then tap Done to return to the app.

Take care,
