Asus India — Asus zenfone 2 4g 32gb silver

Address: 831001

The above product was purchased through snap deal through online purchase. The product was given to service center at jamshedpur to repair defective speaker along with invoice. Now the service center is asking for order confirmation mail when this online order was done & it was told that it is required by asus company for repair under warrantee. At last i could trace a old mail having confirmation of delivery. Even as per service center that is not sufficient. My complain is how you can expect to keep such a old mail unless & until it is specified that warrantee is valid only with confirmation mail? Why the evidence given is not sufficient to avail warrantee support?
