Refusal to return a faulty item

I have purchased an item from Raru that is faulty. I have requested a return within the period for a full refund as per CPA. I collected the item and delivered it back in a worse condition. They are now requesting I must make a video to show the product is malfunctioning. I am now stuck with faulty equipment and I am getting no response from customer care. Rather stick to companies like takealot that don't give customers a run around
