How long have you had it? If you just got it and it is like that, email the guy and give him a chance for a refund. If you have been shooting it for awhile, and shooting arrows that are way too light, maybe you did it. But since you just got if since Christams, email the seller and demand a refund. Maybe he never saw the cracks. Some people are not detail minded and he did not see the cracks. If he is honest he will offer you a discount or full refund. Otherwise, give him bad feedback and contact Paypal if you used Paypal.
