Apple store messed up, what do I do?

I bought an apple pencil in the US for my brother who lives in Turkey. When I went to the apple store I talked to 3 people and showed them the model number of my brothers iPad Pro so that they could tell me which pencil I needed to get. They told me the apple pencil pro, and i bought it. However, they sold me to only pencil that was not compatible. Is there anything I can do or did I just lose 140$ for no reason? :(
