Quality not as advertised- pictures misleading on the website. Owner rude

I bought two separate soap moulds, one blue one and one purple one. The purple mould is of significant lesser quality than the blue mould. The purple moulds buckle in the centre and the corners are not as sharp and uniform resulting in less visually appealing bars of soap once cut. The owner refuses to replace the purple mould for the blue one (despite quality differences pointed out) because she can only replace like for like (in terms of colours) and doesn’t want to adjust her inventory on the admin side of the website- this product is listed as a single product on the website with a drop down box where you can select the colour you want (all the same price), no mention of the moulds being different quality. Very expensive product considering quality varies between colours. I wish the pictures reflect the differences on the website as the photos that are currently up show no difference in quality despite the colour variants- this is false and misleading representation of products in terms of marketing. The owner mentioned to me that I would have to place a new order and pay a delivery fee again (which was R100) if I would like the blue mould because of quality variants so that she would not have to adjust any inventory on the admin side of her shop. Conveniently, after fighting back and forth with the owner insisting she replace the purple mould with the blue mould, the blue moulds are now out of stock. I assume this is so that she doesn’t need to replace my purple one with a blue one and can rather insist on getting rid of old stock of purple moulds that are not the same quality. This owner doesn’t take kindly to feedback and gets annoyed when you contact her on her cell phone number that is provided on the website even if the office line is engaged. Her solution to my issue was that she can only replace the purple mould with the same quality purple mould (because she doesn’t want to do the admin on inventory) which she confirmed are all the same quality as the purple mould I had or to refund me and I could order the blue mould again as a separate order but I would have to pay delivery fee once again, which I was not willing to do at R100 for a replacement item that did not live up to the pictures advertised on the website. I asked that she offer me the refund plus free shipping so that I can place a new order for the blue mould as suggested and she would not have to amend inventory on the admin side of her website to which she refused and said if I want the blue mould I would need to pay for shipping once again. The owner is extremely rude and combative and has no desire to amend the problem with an appropriate solution or to ensure her customers are happy by addressing their feedback in a constructive manner. I would caution you spending your hard earned money here just in case you receive a defective or lesser quality product.
