Looks like you're upgraded through Google Play. You can use the following steps from Alyssa's post here to help cancel.
If you're still having trouble, let me know. 👍
Can you please have your User Support Team contact me in reference to my Pandora and YouTube subscriptions. It seems as though my YouTube Premium account is cancelled, but that my Pandora account is still active (which I'd like to cancel). I've tried everything to cancel this Pandora account via my Google account online. Any support would be greatly appreciated. Thanks

@tdxpecsnomercy I moved your post to this thread since your account is upgraded through Google Play.
You should be able to follow the steps provided in the accepted solution to this thread to cancel your subscription.
With that being said, I will also have someone from our support team reach out to you via email to make sure this gets taken care of as it sounds like you may have already attempted to follow those steps.
Please keep an eye out for their message. 📬
