Apple Watch Band

Hello! I just purchased the apple watch 38 mm series 3 (silver/white band) less than 2 weeks ago. I noticed that the band started turning a yellow/tan color. Being that the product is less than 2 weeks old I found this to be very disappointing. I love the white band and would like to receive a new one if possible. I have the receipt as well as pictures. Please let me know if there is anything you can do to help me with this situation. Thank you so much in advance!
