Amazon refusing to hold their returns/warranty policy and help customer out

I bought an MSI graphics card from Amazon, the graphics card broke so I contacted MSI per the amazon website and MSI told me that Amazon needs to contact MSI and arrange to get the card to them. Amazon does not want to do this and is refusing to help me. I bough the card from them, why is it my job to run around and return it. Amazon shouldn't throw their responsibility away just because it's longer than a month.
