Sold the wrong product and impossible to get a refund or to swop for a correct product as no messages of mine have been answered

I was sold the incorrect product and messaged Clinique on 15 July and have never had the courtesy of a reply and am still sitting with a product that i can't use !!!

Hi There - on Wed 12 July I went into Truworths at Somerset Mall to buy an Aromatics perfume - I chose and small one and the shop assistant offered me the big one in the gift box - and I said I would rather take the small one which I purchased when I got home I threw my till slip away and the plastic packaging and the next day when I opened the box it was deodorant and not a perfume which was extremely annoying and disappointing as the shop assistant had sold me a "Small perfume" I am now sitting with a deodorant that i have no use for Plus i don't have a till slip or the packaging - How do i now swop it for the perfume that i thought I was buying?

I cannot find an SA email address for them and have searched the internet numerous times - the only way i can get hold of them is through their chat on their website
