How do I cancel Apple Music subscription?

I’m trying to add a card to my payment method because I moved to another country. The system says I have to cancel any active subscription before I can change the country/region. I have cancelled all my subscriptions but I can’t cancel the promotional Apple Music subscription. As a result I can’t add my new card from my current country. How do I cancel Apple Music subscription? I don’t see the cancel option. Please advise.
