Unhappy customer

Hi I bought the hydro boost neutrogena face range and I am extremely unhappy with the product it stings my face and has given me red blemishes on my forehead I was recommended this product by one of the sales assistants at clicks I’ve never had a problem with using the neutrogena face range until now I purchased this product about over a month ago and thought my face was just adjusting to it but seems to have gotten worse overtime and no improvement it has done absolutely nothing for my skin and I checked clicks refund and exchange policy and you guys will not exchange or refund me but supposedly claim to do refunds and exchanges if the customer like myself is unsatified with the product it all sounds very contradictory to me how do I know or anyone for that matter know that they are unhappy with the product unless you open it and use it?! I’m now sitting with full bottles and feel like my money has been wasted but more importantly my skin has suffered because of this and now I have damaged skin all because I took and trusted the sales assistant when they told me that it was good for sensitive skin and a good product to use I feel very angered that this product is even on the market!
