Don't be misled by the packaging

I am receiving radiation treatment for cancer on my face and due to gum sensitivity my oncologist recommended I start using Sensodyne toothpaste, so on my way home from treatment on 28/8/2024 I popped into Dischem to acquire some. I saw a tube which in large bold font stated NATURAL WHITE, but to my horror when I opened the packaging (which was sealed, and had to be torn) the toothpaste was BLACK and unpleasant!!! I then wrote a complaint to Haleon (who used to trade as GSK) but many email exchanges later I was informed that as the product was not faulty, they would not entertain a refund, and repeatedly ignored the MISLEADING TEXT which caused me to purchase this product. It seems that although Haleon no longer have ties with GSK, their customer services department still claims to be GSK aligned, based on the email footer, so whether I am being treated like this by Haleon or GSK, it would appear they are one and the same. Why would any company call a product which is BLACK in colour "NATURAL WHITE"?
