Query: less than two months into owning, need new bow

less than two months into owning this instument, a little wooden piece flew out of the bow and now it cannot be tightened, rending the horse hairs too loose. need a new bow. Amazon? I am writing this review bc I did not see a way to "contact seller" which in this case is Amazon! Thanks
