Motor Help

Got my neu 1512 2d in today and hooked it up guess what!!!!! the mm esc is fried it will not arm. Any idea waht I can do with it other than a paper weight to go along with my fried 7xl. I have had this buggy for three months and it has ran for all of 20 minutes before it toasted itself!!!! sorry for all the extra puncuation but this is just a little frustrating. Can I send the esc back to castle to have it fixed?
