Quizlet Charged ₺319 for Unused Subscription, No Refund Issued After Immediate Cancellation

I accidentally signed up for a Quizlet subscription and was shocked to see an annual fee of ₺319 withdrawn from my account. I canceled the subscription right away, as I don’t even use the app and find it unnecessary for my needs. Despite canceling, there’s no option for a refund. ₺319 is a significant amount, and I feel it’s unfair to be charged for something I won’t use. I’ve already uninstalled the app, but I demand a prompt refund from Quizlet. This experience has left me extremely frustrated, and I expect them to address this issue fairly.
