Touche Prive Not Processing My Refund After Return + Not Replying

I placed an order on the Touche Prive website from the Netherlands under order number EU24898 and later decided to return it. I sent the return on 26 September, and according to the DHL tracking information, the parcel was delivered to your warehouse in the Netherlands on 1 October. Despite more than 30 days having passed since delivery to your warehouse, my refund of 239.84 euros has still not been processed. In addition, I have not received any information or update about the status of my return or refund. Over the past three weeks I have emailed your customer service twice and also sent you a message via Instagram, but I did not receive any reply on any of these channels. This lack of response and the delay in processing my refund are causing me serious concern and dissatisfaction. I kindly request that my return be processed without any further delay and that the amount of 239.84 euros be refunded to my original payment method as soon as possible. I also ask you to inform me in writing about the status of my return and refund.
