Personal Narrative: Call Of Duty Black Ops 3

Nearly a month ago I had bought Call of Duty Black Ops 3 at our local Walmart. After I came home I quickly unpacked all of my groceries and pulled out Black Ops 3. I soon started playing and right after my first multiplayer game my screen showed that disk was not reading. I later pulled it out to see it was scratched. As you are aware off it is half to impossible to repair a disk. I tried to return the disk and they wouldn’t take it back. I would appreciate it if you could fix this problem.
