Cancelling your subscription
Canceling your subscription is rather easy. You will just need to go to your manage subscription page where you will be able to view and manage your subscription. You can find that here.
Click the cancel button displayed in the picture below.
Once you click this button, you will be taken to another page where you are asked to give feedback and to click the final cancel button. If you click this button your subscription will be canceled.
Double Check Cancellation
Once you have completed the cancellation process, check the Market place tab on your account and make sure that the status is set to cancelled.
