Amazon India — Amazon is not providing the invoice since last one year

Address:	560068
Website:	www.amazon.in

I bought an Ipod on 9th December 2105. I did not receive any invoice for the product then.

Now, my Ipod has gone bad 4 months back (August 2015) and when I went to authorised apple service centre, they asked me the invoice with serial no. as they were suspecting that the Ipod was not authentic.

Since August I have been contacting the seller, Amazon customer desk. I have written nearly 30 mails, made nearly 20 calls but each and every time I was asked to wait for 2 or 3 days.

Its 8th December today and still i haven't received the invoice and tomorrow (9th December) my warranty would get over. What should I do?

Just because the carelessness of amazon employees and seller, I cannot let my 20, 000 go in waste.

Please help.
