I signed up for a trial of Google Play Music but didn't cancel it before the trial period expired. Now it's taking £9.99 from my card every month. How can I make it stop?
The Google Play support website explains how to cancel the Google Play Music subscription. From your Android device, you do it from inside the settings screen of the Play Music app. Or on a desktop computer or iPhone, you can cancel it through the Google Play Music website.
The first site I linked also has a "live chat" feature. If you need someone to walk you through it step-by-step, you can talk to a Google support person that way.
