Philips Lumea BRI950 Warranty Claim Ended With Inadequate Refund

I purchased a Philips Lumea BRI950 laser epilation device via Hepsiburada on 10 June 2025. Approximately 11 months after purchase, the device stopped flashing. Although my product is invoiced and under warranty, I have been the party who has been victimized throughout this process. After the malfunction, I first took the device to the Philips authorized service in Maltepe. The device stayed in the service for about a week and in the end I was told that they could not replace it because they did not have a new device in stock. They stated that this model is not repaired and that only one-to-one replacement is performed. They also gave me a dealer replacement form and informed me that I could have the product replaced by the dealer from which I bought it with this form. After that, I contacted Hepsiburada. They did not share with me the information of the dealer to which the product was sent, but they opened a request record, gave me a cargo code and asked me to send the product to them with this code. I was told that after the inspection of the product, a new device would be sent to me. I clearly stated that I did not want a refund and that I requested a new product. Since it was said that a new product would be sent, I sent the device to Hepsiburada. After about five days, I received a notification that a refund had been processed for me. The refund has not yet been reflected in my account, but I saw that the refund was made based on the old price at which I purchased the product 11 months ago, which is ₺14,613.90. With this refund amount, it is not possible for me to buy the same device again at today’s prices. Even though my product is under warranty and the fault is not caused by me, I have again been the one who suffered the loss. I opened new requests via Hepsiburada and today I spoke with customer service again, and I was told that my request was updated as “urgent”. However, for days I have only been hearing the same sentences and I have not received any concrete solution or feedback. My request is very clear: either a new device of the same model should be sent to me, or the current amount that would allow me to purchase the same device today should be paid to me. If this process is left inconclusive in this way, I would like to state that I will resort to all necessary legal means to eliminate my grievance and seek my rights.
