Sürat Kargo Sent My Istanbul Package to Ankara and Provided No Solution

Here's the translation of the text from Turkish to English:

"My package has still not been delivered to me, and on top of that, the solution center is sending me an email saying that the status of my package could not be determined. I am supposed to request a refund from my seller, even though the responsible party for my undelivered package is Sürat Kargo. I don't understand how they can blame the seller for this. Sürat Kargo is basically telling me, 'We lost your package, we don't know where it is right now, but go and ask the seller for a refund.' What kind of sentence is this, what kind of request is this? The solution they found could only be this anyway, what kind of work ethic is this?"

Even though it's been 8 days, my package still hasn't been delivered, and the mentioned shipping company has not provided a solution. Not only have they not provided a solution, but they also haven't even contacted me. I received a response to the email I sent 3 days later, and their reply was that I could contact their call centers. My complaint was already that I couldn't reach anyone regarding the issue through the call center or any other contact addresses, and they responded mockingly to call the call center. Currently, I can't even see where my product is using the "where is my package" application. My grievance, which needs to be resolved, is increasing day by day with accumulating errors.

Although today is the 21st, my package is still showing as being at the the distribution center. The package, which was supposed to be delivered to me two days ago, has not arrived. As the dress I was planning to wear today was in that package, I had to go to the store in Nişantaşı and repurchase the same dress for ₺13,500. I am requesting compensation for my loss. There seems to be no resolution for this negligence, and there isn’t even a proper department to contact for assistance.

I submitted a complaint to Sürat Kargo, but there has been neither a response nor a solution. An urgent and important shipment that was supposed to be delivered yesterday still has not been delivered today, and there is no one I can even speak to about the matter. My emails and phone calls have gone unanswered. The live support line is not available, and when I went to the branch where my package is supposed to be, the staff there said, "God knows which vehicle it’s in." What kind of service is this, and how can a company claiming to be corporate operate this way? What more do I need to do to resolve this issue and address my grievance?
