Datawind Aakash — NON DELIVERY OF MY BOOKED TABLET EVEN AFTER ONE YEAR

I had booked a Ubislate Tablet 7+ for delivery in May-2012. However, it has not been received till date. The booking no. is given to me was PM2C56C. However, on subsequent e-mail correspondence with the company, they had offered me alternative model at additional cost which I have not received till date. On entering this booking no. on their site it shows the status that they have delivered the material to someone else. Company may give me now any other improved model at the earliest. I have already prepaid (vide HDFCBank cheque no.035639 on10.05.2012) the required amount at that time and my deposit has earned more than enough interest by now.
