No foresight or understanding of medical challenges

I suffer from severe osteoporosis, which means I fracture my bones very easily. Recently I ordered a Walking Pad R2 Pro from Takealot. I fractured my ankle severely after I placed my order. As my husband (a doctor) had left for Turkey with a rescue organisation, I was unable to open the box. When he got back and we opened it, firstly it was clearly not packaged properly. But that was not the main issue. The thin frame and uncushioned pad was deemed totally unsuitable for someone with my condition. I put it back in the box and logged a return. Not only did takealot not refund me based on extenuating circumstances and medical reasons, they didn't even communicate this to me. Nor has any plan been made to return the item for me to sell privately. I have legal recourse in this situation as I was severely injured with the same injury which makes this piece of equipment unsuitable for me from a medical point of view. Why else would I return such a great-looking walker unless I was forced to?? I would like takealot to look at my case as unique and under extenuating circumstances and to show some understanding and compassion towards this case. This walker is unsafe for me and if, after telling takealot this, I injure myself using it, it will be on the shoulders of takealot. Please may I ask somebody to look at this case again and consider my individual circumstances. At the very least, replace the item with a new one and deliver that to me so that I can try to sell it myself. I have medical evidence that I have been advised against using this walker due to its lack of support and cushioning. I am a loyal takealot customer, which can be verified by my purchase history. This is no way to treat a medically-challenged customer. Please can somebody get back to me urgently.
