Dear Rungnapha,
Please be advised that the Refunded Returns service applies exclusively to return shipping costs for tangible items sent back to the merchant/seller, not to payments, original shipping, purchased products, or services.
Since your claim concerns a payment, we advise you to contact Twitch or PayPal Customer Service directly at https://www.paypal.com/selfhelp/home for a more detailed response.
We wish you the best of luck.
