How would you react if someone didn't appreciate your gift?

My friend and I have been living in different countries for years. This year, for her birthday, I decided to surprise her and send her a gift (a necklace). Yesterday, she received the gift. She sent me a text "Hey, I got your gift". Not even a simple thank you. It really hurt my feelings since I spent a lot of time and money to get her a nice gift even though she NEVER bought me anything. How would you react if you were in my position?
