i need help cancelling subscription MLB.TV

I need help making sure that I cancelled MLB.TV. I signed up for it as a 7-day trial and then immediately cancelled it because I did not want any hassle cancelling it. Now I was billed for it. I followed the instructions and I saw no additional place to cancel, so I assumed it was cancelled.

On my iPhone. I still see under Apple ID / Subscriptions / Active: MLB.com (I do want to keepe Hulu).

I appreciate any help!

Thanks,
