Subscription

If you have a problem with a subscription or a purchase, see Subscriptions and Purchases https://support.apple.com/en-euro/billing. If you think you may be able to get a refund, then use the request a refund link. It will take you to Request a refund for apps or content that you bought from Apple https://support.apple.com/en-euro/HT204084

See How long refunds from the App Store or other Apple services take https://support.apple.com/en-us/HT210904

You also can get Apple telephone support for help in solving your problem using this link https://getsupport.apple.com/?caller=kbase&PGF=PGF63005&category_id=SC0245&symptom_id=23362  Be patient; sometimes you can't get immediate telephone support.

You also can use Apple Support Twitter  https://twitter.com/AppleSupport. There may be an hour or so wait.

And here is how to contact iTunes worldwide support via text or chat using this link https://support.apple.com/choose-country-region/itunes. After choosing your country, see the heading Tell us how we can help.

Not sure exactly what you want to do, but it sounds like you want to cancel a subscription of some kind and this should cover it. If cancelling is more what you had in mind, then try this.
