Amazon Seller Refuses to Refund My Defective Dyson V10 Attachment

I purchased a Dyson V10 vacuum cleaner floor head from the seller Supervac through Amazon. The product was delivered on October 20, 2026. Over the following 20 days, I used it only about 5–10 times in total. During my last use, the brush head suddenly stopped rotating. Although the motor inside the attachment is running, it no longer has enough power to turn the brush, making the attachment completely unusable.

After this happened, I contacted Amazon customer service, but they refused to accept my return request. When I contacted the seller, Supervac, they shifted the responsibility to Amazon and stated that they could not accept the product back. I paid $92 for this product, yet it broke down within just 20 days, and neither a return nor a replacement is being offered.

I have been left out of pocket because both Amazon and the seller keep passing responsibility to each other. I honestly feel misled and cheated by the way this situation has been handled. Considering that the product broke down within just 20 days of delivery, I demand a full refund for my purchase under order number 171-8859891-3268363.
