If you want to cancel your subscription, go to ACCOUNT --> Settings --> Manage your subscriptions.
Then select the CANCEL PLAN button.
Important:
If you want to be sure that your subscription will not be extended for the next billing period, cancel your current subscription at least one day before its end.
Deleting your account does not disconnect your card. If you want to completely delete your account and you have an active billing period, remember to disconnect your card by canceling your subscription.
