Duolingo Charged My Card Without a Clear Confirmation

I started a one-week free trial for a Super Duolingo subscription. I did not realize that I would be charged at the end of the trial, and afterward, 1,209.99 was charged to my account without my permission or authorization. The payment was processed through Apple.com/bill using my card ending in 0019.

I do not accept being charged this amount without seeing any additional confirmation screen or receiving clear information about the charge. Being automatically enrolled in a paid annual subscription after the free trial and having such a high amount charged to my card without my knowledge has caused me financial harm.

I request that Duolingo issue a full refund of the 1,209.99 charged through Apple and cancel my Super Duolingo subscription.
