Color Widgets - Charged AUD $32.99 Despite Selecting Free Trial

This is a total scam.

1. I downloaded Color Widgets and selected the 3-day free trial for the one-year subscription.
2. I was charged $32.99 immediately, no free trail.
3. I contacted Apple Support to request a refund, but they denied my request twice.
4. I reached out to the Color Widgets Support Team, explained the situation, and was told to ask Apple again.

What should I do?
