Datawind — non delivery o[censored]bislate 7c+ even after 20 day of payment

Address:

Howrah, West Bengal

My name is Sunil Gupta and I had booked ubislate 7c+ tablet through datawind site dated 17th April 2013.Advance online payment was made through my HDFC credit card. Rs 4899.00 got debited from my account as the said tablet price was Rs 4999.00 and Rs 200 was charged for shipping. I got discount
of Rs 300 by using a coupon which I got from one of datawind promotional mail. It was clearly stated in that mail that the device is available for immediate delivery and will be shipped within 72 hrs.Today is 06rd of May and even after 19 day I have not received the tablet.

My booking id is PMD1BB8 and while checking the booking status it always shows that ”Dear Sunil Gupta Status of your Ubislate7Cp is Hold ”. I can't understand that what does it mean by ““HOLD” .Datawind's Concern department has not yet dispatched the tablet even after 19 day of successful advance payment.
I have twice mailed the issue with my order id and contact no. to [protected]@datawind.com without any reply. Helpline of datawind is also not answering after consistent try.
What should I do now. Should I have to go consumers court?
