How do I cancel a free 7-day Premium subscription?

Question

I've been trying to cancel the 7 day premium subscription, but there's no option I see at all to cancel it.
All I see is this when I go to Manage my account/subscriptions
I understand that it's free, but I know that a 30-day trial, you have to pay after the 30 days unless you cancel during the free trial. Will I really have to pay unless I cancel this, or will it just return me to a Spotify Free account?
I don't recall having to put in credit card info, because it had been on my mobile device. (I accidentally clicked the button to get me the 7 day trial... my bad )

hello   
The Spotify free premium trial cannot be cancelled, but dont worry its free so you wont be charged unless you gave payment info :) 
if you gave payment info you can cancel your subscription by doing this:
Canceling your subscription reverts your account to the Free level.
Go to the subscription page. (Note: If you don’t know your password, go here to reset it.)
Under Subscription and payment, click cancel your subscription.
Select a reason (select Other reasons if you're canceling for a promotion). Click CONTINUE.
Click CANCEL MY SUBSCRIPTION.
Enter your password in the password field. Click CANCEL SPOTIFY PREMIUM SUBSCRIPTION.
Your subscription page now shows the date you will revert to our Free ad-based service. We hope you decide to upgrade again!
Note: If you subscribed through any other company than Spotify, you need to contact that company to cancel. If your subscription is through iTunes, please see Apple's instructions for canceling.
