Yes, you can turn off auto-renew at any time but remember to do so at least one day prior to the end of your current subscription period - or free period of access - to prevent any further payments being taken.
Except as described here, once you have turned off auto-renew, you will continue to be able to use your GOLFTV Pass until the end of your current subscription period - or free period of access.
Note: You can only manage your subscription settings - including turning off auto-renew - on the billing platform through which you made your original purchase.
