Royal Enfield — chassis cracked / frame cracked

My 2014 model royal enfield desert storm 500 chassis has cracked. I have tried to weld it but the crack is on both the sides so it is not repairable. I was lucky to notice well before riding or else would have met with some accidents. I have never heard or seen any kind of this proble in any other bikes. This is purely a manufacturing quality issue. I need the part to be replaced by the company. Pleae help.
