Dyson V11 Battery Failure – Request For Free Replacement

I am writing to express my disappointment with the service I have received regarding my Dyson V11 vacuum cleaner. I have only been using this product for three years, and its battery has already stopped working completely. The vacuum cleaner does not respond at all. When I contacted Dyson customer service on November 3, 2026, I was informed that I would need to pay over $100 for a replacement battery. For a premium product such as Dyson, I find it unreasonable that the battery has failed completely after only three years of use and that such a high fee is being requested. I expect Dyson to take responsibility for this issue and repair my vacuum cleaner or replace the battery free of charge. I kindly request that my case be reviewed and that a fair resolution be provided as soon as possible.
