Misrepresentation

I have been trying to obtain from Dischem and the company that supplies them with their Bionike skincare range that Dischem are marketing as being safe for cancer patients to use and they just ignore me. Do they have something to hide? I am an advanced Aesthetician and patients undergoing chemotherapy and radiation have to use skincare that is totally suitable and safe with clinical data to show for this, during this time. Dischem are marketing imported products from Italy that I have researched and I find are totally toxic for cancer patients to used during cancer treatments. I have asked to view their research data, or obtain someone who could give me scientific answers which have to be made available to the public, but the company in Italy refuse to answer my enquiry as to if their products ARE safe to use DURING chemo and radiation, the same as Dischem here in Johannesburg, I have researched the ingredients on a few of the products they are prescribing for cancer patients only to find that the products in fact could do great harm to ANYONE using it. I look forward to being proved wrong!
