Hello, I have a racket that is 1-2 months old. 1 week ago when I played with the racket, during the warmup. I heard a strange noise. I continued to play, but after a while I noticed that my racket was sounding very strange. I had a look at the racket and found that the shaft had a crack See picture Can I claim this on warranty? I had a clash before on the racket head, but that should affect the shaft right?
