Please read the subscription terms that you agreed to when you signed up for the annual plan, paid monthly. You have two weeks to request a cancellation without penalty, and you say you have had it for 5-6 days.
From the first day you downloaded it, you have 14 days in which to cancel & receive a refund on your Photography Plan. After 14 days, you must pay an early cancelation fee which is 50% of your remaining months of service. To avoid penalty fees, simply wait until your 12th month of service to cancel.
