If you signed up for the free trial that you can “cancel in Settings”, there is no option to cancel the subscription, and no way to say no to the subscription unless you leave CleanWave when it prompts you, THE FIX: Report a problem as scam/fraud in CleanWave Store, submit it, and on that same submission success page you can see Pending Purchases. Find Speaker Cleaner and click Details > Manage Subscriptions > Cancel Free Trial/it’s a red cancel button, all of this is inside the apple support safari page it opens when you report a problem from CleanWave store! Hope this helps lost souls like me
