HP India — unable to claim extended warranty

Address:

Hyderabad, Andhra Pradesh

After claiming for extended warranty by uploading the required details and paying the amount i received a mail after 3 days saying that my bar coded serial no and the invoice are not received and the mail included that i have to upload them again within 10 business days. So where should i upload or mail my details???
None of the service center is looking after this.
So please resolve it.
