Amazon India — Order cancellation and refund problem

I had placed an order[protected] for luminous inverter amounting 20456/- INR on 26th august. After complaining for 15 times I have not received order and tracking id is invalid. I wanted to cancel but that option has been removed. I have been asking for refund but amazon says now the query is being handled by social media team and they cannot do anything.

I trusted with a big amount and now struggling to get a response. Seller provided a fake delhivery tracking id and amazon social media team cannot be contacted as they dont have any direct helpline. No body is responding to my queries. This is a scam
