Re: "why am i been charged for an app i didnt purchsee? now it is labeled as owed?"
Seems a free trial needs to be cancelled at least 24 hours before expiry, if you do not want to be charged.

We are all Apple users, like yourself in the community, so we have no access to your accounts or details.
However: If there's a problem, your screenshot shows you can: "Report a problem" via a link:
To report a concern about an app, you must provide the URL of the app.
See how to: Find the URL for content to report a concern - Apple Support
Report a problem: https://reportaproblem.apple.com/?s=6
As far as I know there is no way to claim a refund, unless money has been paid.
If you want to contact Apple: You could contact Subscriptions and Billing Support (online chat / phone / email):
There is a “Get Support” Link (or an App you can download) at the bottom of their webpage.
Website: Subscriptions and Billing - Official Apple Support
If needed: Contact a third-party vendor:
The best source of help for a product not made by Apple (a third-party product)
is the company or person who made it—its vendor or developer:
