ShopClues.com — Not providing invoice for hp printer

Address:	700091
Website:	shopclues.com

I have ordered an hp deskjet ink advantage 4535 wireless all-in-one duplex printer from shopclues.com on oct 8th & received the product after a lot of delay on oct 21st that too after numerous follow-ups with the courier services. the product came in a bad packaging & seems like repacked by the seller. there was no invoice provided and without that i will not be able to claim manufacturer's warranty which is of 1 year. i have called up the customer care many times but they just keep asking me to wait from n number of days & extending the days when i am following up. i even called up the seller directly, his behaviour was rude & i was said that 'you should have collected the invoice from the courier", now i really doubt the authenticity of the seller & shopclues.
I have attached the bill which they have provided through their website.
Pathetic customer support & i think no one should buy anything from shopclues because its a fake.
