I bought a NIB Cell and just recently drilled it up in April of this year with a strong drilling for strictly a heavy oil piece. I bowled 2 tournaments with it for a total of 9 games. My equipment is kept inside and as I was moving things around the other day, I noticed an inch and a half long crack that extends from the top of my ring finger hole over to the pin and half way around the pin. The pin is over an inch from any hole in the ball. Since I bought the ball from an individual and not a pro shop, even though the ball was NIB and I have all recepts and documentation, does anyone know how I can get this replaced with something similar if the pro shop that ordered the ball from roto grip originally cant be located? This definately sucks Roto Grip. Thanks for any help.
