Dyson Airwrap Replaced Product Failed Again

I purchased my Dyson Airwrap id from Dyson’s official website on November 29, 2024, for ₺20,000. On September 11, 2025, I had to send the device to service because the attachments were not staying in place. The service replaced the device and sent me a new one. However, on March 13, 2026, the replacement device stopped blowing hot air and I sent it to service once again. Since then, I have been waiting for an update about my device and have had to constantly ask about its status almost every day, yet I did not receive any clear or timely information. After this long waiting period, today I was informed that instead of repair or replacement, a refund would be issued. This decision is a complete disappointment for me. I bought the device in 2024 for ₺20,000, and its current sales price is ₺27,000. Not only have I been kept waiting for days without proper communication, but now I am being offered a refund based on the old purchase price. I have clearly stated that I do not accept this and that I either expect to be provided with a new device of a higher model or to be paid an additional ₺7,000 together with the refund so that I am not financially disadvantaged. It is unacceptable for the consequences of a low-quality and repeatedly malfunctioning product to be imposed on the customer. I request that my grievance be resolved urgently, that my order with tracking number B012024001106470 be handled fairly, and that either a new device of a higher model be provided or the ₺7,000 price difference be compensated along with the refund.
