Amazon India — Non-refund o[censored]ndelivered order no.[protected]

My registration customer id is [protected]. I booked split ac on 6th march and paid rs 27990 online. It was scheduled for delivery on 8th march. On 13th through an email i was informed that if it is not delivered by 16th i may take money back. On 16th customer desk, on chat, confirmed that the order is lost in transit and money will be reverted back to my account. He also said i don't have to do anything in the matter and company will do refund exercise on its own. He also promised to put in rs 100 as some sort of solace to me for my loss. But after that i have been contacting the customer desk daily, without any success. Standard reply i get is that large appliance section has escalated the matter and as soon as they get update, refund process will be initiated. But when will this take place, is not replied. They are not ready to even give number of some senior official who may be contacted for help. So company must pay me back rs 27990 expiditiously.
