Touché Privé Unresponsive on Email and WhatsApp After Retaining My $20

I created a return request under order number #1009405 for a belted linen dress (Camel, Size L) purchased from Touché Privé. On June 8, I initiated the return process following the provided instructions and shipped the item on the exact same day via Aras Kargo addressed to Touché Tekstil A.Ş.

I paid the product price of $20 via credit card. Despite contacting customer support multiple times via email and WhatsApp, I have received no response for two months, and my refund has still not been credited to my account. I am left in a difficult position due to the complete lack of communication regarding both the returned product and the monetary refund.

I do not accept that my payment has still not been issued long after my return was received. I demand that my refund of $20 be urgently credited to my credit card and that written notification regarding the process be provided to me.
