I've tried for the past month to cancel the Google Play Pass that I had a free trial for, however initially I kept getting some technical error message saying there was an active transaction on my account and I needed to try again. Now, that message is gone but the Cancel Subscription link is inactive

How can I cancel the subscription if Verizon won't let me, and Google says I need to manage the subscription through the 3rd party... which is Verizon, who won't let me cancel?
