I have booked a Ubislate 7+ on website www.datawind.com by booking ID is "PM86F45C614". It was Booked on June 23, 2012.

for Ubislate 7+.
I request Company that please send this Ubislate 7+ to my address As soon as possible.

Company had promised to deliver Ubislate 7+ in month of August.
But company had not sent the product till October.

Later company had offer an upgrade offer from Ubislate 7+ to Ubislate 7ci which will be shipped within 72 hours


So I accepted the offer.

But till date company had not shipped the product and beating about bush.
I have sent to company Full Advance Payment by a cheque(SBI) No.370457 of amount Rs 2999,Dated[protected] for Ubislate 7+

which was,according to offer, upgrade to the UbiSlate7Ci, the extra charge is only Rs.500, payable at time of delivery.

on Jan 3,2013 company told (on my mobile) me that your product is being sent to you by courier service and will reach to you within a week at Address Sh Amar Singh Beniwal Advocate,Ram Colony, Barnala Road, SIRSA-125055, Haryana.

But product has not reached yet.

I want to know when the product will be delivered to me? Please also inform me Address and Contact number of courier service with shipping detail if any, so that i can contact the courier company.

I think company has taken my money and making me fool by not delivering product.
Please help me.
