I bought a black iPod touch 5g last Thursday from challenger . However, the next day when I decided to recheck the iPod touch, I spotted scratches on the back of the iPod touch . Those scratches looked like its been dropped . I also didn't have the time to go back to challenger as its too far away from my house . I manage to go challenger yesterday to demand an exchange . To my surprised , that lady said it is not possible for exchanging . That lady said I could return if there are any scratches found in 7 days when I bought it last Thursday . She said I should go to Apple to demand an exchange instead going to them . What can I do???
