If you purchased your The Tapping Solution App subscription through the mobile app via Apple/iTunes, any refund requests must be handled directly by Apple. Only Apple Support can issue refunds for purchases made through an Apple ID.
To request a refund, please contact Apple Support here:https://support.apple.com/contact
We also recommend canceling your subscription so it doesn’t renew and charge again. You can do this by turning off auto-renew in your Apple ID subscription settings (Settings → [your name] → Subscriptions → The Tapping Solution).
