If it is new and you set it up correctly then the manufacturer's warranty should cover it. It was most likely a manufacturing defect that caused the rod to delaminate. Call customer service.
As a point of interest if they say no, please post who manufactured it (and under what brand), where you bought it and if they gave you a reason. I would want to stay clear of a manufacturer/retailer who doesn't support their product/customer if that's the case.
