how do i fix this apple subscription thingy?

Problem/Goal: I forgot to cancel a free trial for an ad blocker + VPN app, and it renewed into a ₱2,490/year subscription. I want to know if I can still get it removed or refunded and fix the billing restriction on my Apple ID.

Context: My GCash had no funds, so the payment didn’t go through. I already canceled the subscription after noticing, but it still shows “Subscription ends May 21, 2027” and my Apple account is now restricted (can’t download or update apps).

Previous Attempts: I’ve already canceled the subscription right after noticing the renewal. I haven’t used the app after it switched to paid.
