Duolingo Charged ₺1200 Without Notice After Free Trial Ended Late at Night

I got a free trial from Duolingo, so I decided to give it a shot to work on my English skills. But after the trial was over, I got charged ₺1200 at 3 a.m. without my okay or any heads-up. I can’t believe this happened, especially since the app said they’d let me know when the trial was over. This surprise charge is a big issue for me since I don’t have a regular income. I'm going to bring this issue to the Consumer Arbitration Board and the Human Rights Commission because I think this way of handling things is unfair and misleading. I thought Duolingo would be honest with me, but now I feel like I've been misled. I didn’t think I’d be treated like this by a learning platform.
