You are not talking to Apple or iTunes Support on these forums, just fellow users.
But accidental damage isn't covered by the warranty, and as the iPad is basically a sealed unit the whole iPad is replaced, not repaired.
You could see if there are any repairers that will replace the glass on it - that will probably be cheaper, but any unauthorised repairs will void the remainder of its warranty.
If you want to contact Apple, then assuming that you are in India as you've given Rupees as the currency, then there is contact info on this page : http://www.apple.com/in/contact/
or there is a phone number for Apple India on this page : http://support.apple.com/kb/HE57#I
