Dyson Did Not Deliver The Product And It Was Shown As Delivered

I am extremely disappointed that my order number 679 480 848 from the Dyson store on Hepsiburada has not been delivered as promised. Even though I made a request, they denied my claim, stating that a mere photo of the package was sufficient evidence of delivery. Simply providing a photo of the package is insufficient evidence, as deliveries are verified using a T.C. number or a code sent to the phone. The customer service at Hepsiburada appears to be unaware of this, resulting in an unfair decision. I kindly request proof of the delivery of the ordered product and will consider taking legal measures if necessary. The courier claimed the package would be delivered the next day after an alleged breakdown. After countless phone calls and assurances, the product has yet to be delivered. Attached are all the communications for your reference. What's the point of having numerous phone calls just to ensure a smooth delivery?
