Origins Seller Sent Someone Else's Invoice for My Trendyol Order 11220156852

I purchased the product set titled "Ginzing™ Jumbo Set: Gel Moisturizer 50 ml & Eye Cream 15 ml with Vitamin C & Niacinamide" under the Origins brand on Trendyol. However, one of the two items included in the set was sent incorrectly. Although the listing image and description clearly present it as a set, one of the products that came out of the box does not match what I ordered.

I reached out to the seller via message on Trendyol and received a reply about 5 hours later. My previous question in the Q&A section went unanswered for a long time as well, leading me to believe I was deliberately kept waiting. I also made contact via email during this process, but only received generic, canned responses without any real solution.

Finally, a very brief and inadequate response stating "you can return it" was sent via Trendyol messages. When I spoke with live support, I was asked to check the invoice. Upon inspecting the invoice, I realized it was issued not to me, but to another individual named "Y***** B". It is very obvious that shipping barcodes were mixed up. While I could view sending the wrong product as a simple human error, I refuse to accept the lack of communication, delayed responses, and constant resistance to providing a real solution.

Furthermore, I opened and started using the correct eye cream included in the set. Because the products were sold together as a set, telling me "you can return it and repurchase if you want" is neither a realistic nor a fair solution from my perspective. I do not understand how I am expected to return a set when I have already opened and used part of it, nor why I should be forced into a return in the first place. If an exchange option had been offered, I could somewhat understand, but the current approach solely demands that I return the set and buy it again.

I feel entirely victimized by this process. I placed my order under the name N*** Ş**** P**** with order number 11220156852, yet a completely different name appears on the invoice. While even small vendors strive to resolve issues without victimizing their customers, I never expected this level of service from a brand I considered corporate and prominent.

My primary demand is the immediate dispatch of the correct product to replace the incorrect item in the set I purchased. If this cannot be provided, I demand a full refund of the total price paid for the set. I expect my grievance to be resolved swiftly with proper customer care.
