Incorrect product given at purchase

I went to Fabiani Mall of Africa on Tuesday to buy Wonderoud by Comme des Garcons and I chose that one specifically when I asked the lady at the till. Trusting that she was put there and knew what she was doing I didn’t double check my purchase. I was too excited to say the least. Today, 5 days after my purchase I looked at the bottle since I could tell the scent is not what I wanted and it turns out I was sold Wonderwood instead. Kindly contact me so that we can rectify this mistake
