Pathetic Mineral Foundation

I went to Edgars Galleria Mall to buy lipstick. I was there for a wedding. The lady at Elizabeth Arden made me buy lipstick and this Finish mineral powder and I had my Mac foundation on that looks good for my complexion. I took it thinking it will look nice but I saw when I was back in Jhb that it's too light for skin color. I took ot to Edgars Sandton and their white manager said no I can't change cos I used it. I told them I used it once only and saw it's too light and also I never buy make up at Elizabeth Arden. But cos I removed the box in Durban to make space in my luggage they said no. This make up is very expensive and for them not to understand and exchange it for my skin tone is unfair. I don't know much about make up hence I stick to Mac the biggest problem I made was too forget my lipstick in Jhb
