I Face Hair Damage and Refused Return on My Dyson HS06 Hair Straightener

My grievance with this company is still ongoing. No one from the company has called. They only care until the sale; after that, the customer is left on their own.

Trusting Dyson’s '14-day unconditional return' promise on their website, I purchased a Dyson hair styler/straightener from the Dyson İstinyePark store in April 2025, paying approximately 21,999 TL. When I used the product for the first time, I noticed that in less than 10 minutes my hair shriveled and burned like corn silk. Seeing that it damaged my hair, I immediately stopped using the product and wanted to return it. The İstinyePark store where I bought the product directed me to Dyson, stating that they were not authorized for returns. When I spoke to Dyson by phone, everyone I spoke to almost repeated the same sentences as if memorized, saying they would not accept the return. Because the 14-day unconditional return promise clearly stated on their website was not actually implemented, and I kept hearing the same stereotypical responses throughout the process, I feel both deceived and not taken seriously. Since I only used the product for a few minutes and immediately stopped, and despite contacting the store and Dyson multiple times I could not get a result, the process was prolonged and this time I was told I had missed the return window. Despite all this, I applied to the Consumer Arbitration Board to seek my rights, but I could not get a concrete solution from there either. My receipt number is 0043, and I am seriously aggrieved because a product I paid such a high price for both damaged my hair and its return was refused. I demand that Dyson stand behind the 14-day unconditional return commitment on their own website, accept the return of the Dyson hair styler/straightener I purchased, and refund the full amount I paid. I expect them to be transparent and fair to the customer and to adopt a consumer-friendly approach. Although I already have two Dyson vacuum cleaners at home, after this grievance, I will have to think many times before buying any Dyson product again; I especially want to state that the distrust and financial and emotional damage I experienced in this process have completely negatively affected my perception of the brand.
