I would like to inquire about payment.

I saw a discount of $2.99 ​​USD for a one-year initial subscription when I signed up. However, after the 8-9 day free trial, I realized I didn't receive the discount. I've contacted several places, but haven't received a response. This is the only place left, so I'm asking here.

As you can see in the image, the payment processed was a full amount.
