Most charges are subscription renewals or purchases connected to your account. Charges may come through FT Streaming directly or through an app store, depending on where you subscribed.
First, check your account billing area and any app store subscriptions connected to your devices. Also confirm whether more than one email may have been used.
If you do not recognize a charge, contact info@foundationtraining.com with the charge date, amount, last four digits of the card if available, and the email addresses that may be connected to the account.
