Trendyol Lost My Order and Delayed Refund Despite Repeated Complaints

My order from Trendyol with number 11584037298 was supposed to be delivered on 12 September, but it never arrived and I was later informed that it was lost. Since then one month has passed and my money has still not been refunded. The total amount I paid for this order was about 8 euro. I contacted Trendyol customer service and only received answers from a chatbot that keeps repeating the same messages without giving any real solution, refund, or clear information. Because of the lost order, the long delay, the lack of proper support and the misleading answers, I am very disappointed. I request an immediate full refund of the 8 euro and an additional compensation for the wasted time, stress and false information I have experienced in this process.
