Dangerous Article Sold

Date: 9/14/23 Order no. 750485 Your waybill / tracking number is: Z***. Just delivered. 9/29/23. Chair not workable. Chair wheels will not engage. Want to return and receive a refund! Very dangerous. Reply From One Deal A Day "No problem you may send it back to us using your own courier of choice and book this in at your cost (NON REFUNDABLE)." Why should I have to pay courier fees to return. Furthermore the box that they delivered the artificial in was old broken and taped so much that I had to break the box to get to the article that was wrapped in a black plastic bag with lots of tape. I have repeatably requested a answer, can only request on WhatsApp , and now being ignored. What can I do with goods that are unusable and dangerous to use?
