Datawind Ubislate — product not delivered even after payment

Address:

Amravati, Maharashtra

to
the concerned authority,
I, Nikhil Dhande, had ordered Aakash 2 (ubislate 7c+) after receiving an email from datawind, in which they stated that the product is ready for delivery.
I completed online order procedure and online payment on 9th march, 2013. but till date I haven't received the product. so I think that they are not at all interested in delivering me the product.
therefore I request you to compel them to REFUND ME RS. 4799/- ASAP (without any deduction as stated in their norms about refund and cancellation).
Thanking you in anticipation
