Subscriptions refund: Report a Problem shows no eligible

Hi, I really need help with a subscription billing issue.

I was charged for subscriptions I did not intend to keep, and some of the charges were processed automatically without me realizing they were renewing.

When I go to Apple’s “Report a Problem” page, it now says:

“You have no purchases eligible for a refund.”

I already contacted the app developers (YouCam Video and YouCam Perfect/Edit), and they told me only Apple can process the refund because the payments were made through Apple billing.

1. Is there still a way to request a manual review from Apple even if the refund page says no eligible purchases?
2. Would contacting Apple Support by phone/chat help more than the website?
3. Does cancelling the subscriptions affect my ability to receive a refund?

Any advice would really help. Thank you.
