If you take advantage of the free trial when registering for the service, the 14-day cancellation period will start from the day Playstation accepts your free trial order, and the duration of the free trial will be included in the 14-day period. For example, if you sign up for a 7-day free trial and charge your subscription through your payment method at the end of the trial, you will have 7 days to cancel your subscription from the date of the charge.
