Wrong foundation color

I went to Kollonade mall in Edgar’s store yesterday to buy a Estée Lauder foundation for my face, one lady assisted me (after I waited for 10min) she used a machine like object to check what color should I use. She gave me a bronze double wear 5w1 , but it’s dark . I’m now stuck with a dark expensive foundation that I’m not gonna use because I believe that lady knew what she was doing, I’m only seeing it now while I was applying my makeup. I’m deeply disappointed. I normally use Mac NC44 but I wanted to try something new, but hey what a disaster
