ZOTAc - RMA not provided

Purchased a graphic card worth **k inr near, in ****, came with * year warranty, with * year extended if register product with ** days of purchase on their zotac website which i did, they are denying the RMA request since it stopped working randomly, back to it telling me product sold was too old stock from reseller side despite i contacted zotac USA live chat and they said it doesn't matter as long as it was newly purchased from reseller, old stock doesn't matter. Reseller isn't supporting either and stopped taking my call
