Sold wrong make up colour

I went to the glen coaching to buy este Lauder double wear make up and I was approached by their make up artist who checked my skin colour and advised me to buy the colour and I had concerns but the other lady working there as well and said no that's the right colour for me and it's so expensive but I bought it and now putting it on this morning the colour is so dark and makes me look dark and everyone around me say I look dark and I'm so angry as I told them and they told me otherwise as they are experts in the field and now I'm stuck with something I'm not happy with and paid a lot of money for.im bitterly disappointed and want my money back or the right product
