i red somewhere in this forum that hpi will replace the original rush chassi for the Evo one?

but i called them 2day and they said its my fault because i bent the chassi and they said they never remplace them for free?

is there something i could do to make them send me a new one? could somewhere send me a link on hpiracing where it said they would replace it free of charge? cuz i was looking for it for hours
