Why I can't see purchased in the subscription list in my Child and Parent (me) account? It's scammed?

Over 2 years. From my children account (as payment sharing) to my account (as parent), I đin't see three apps: eChat Keyboard, VIP Program and Math Plus in the Subscription list and still charge until I must go to reportaproblem.apple.com to checked it.

And after that, I also cannot see the "Cancel Subscription" button any where.

Specially, "Vip program" and "Echat Keyboard" app charged every week. It's terrible and stolen about 1.000$ from me.

I need clearly for next experiment in more carefully.

Here is my screenshot for scammed app:

Thanks you.
