Datawind Ubislate — no refund even after 17 months

Address:

Erode, Tamil Nadu

Dear sir, I booked 2 ubislate tablets and paid the full amount of Rs.6000 for prioritized delivery on 2.2.2012.
Our pre-booking reference Nos. are PM0BF22 and PM08BD9. Since it was not delivered for more than 9 months and since they offered to deliver immediately i[censored]pgraded, we opted for upgrade 19.11.2012, this was upgraded to Ubislate 7ci with booking ID PM2933F. It was cancelled on 21.11.12 since there were too many complaints about that product by the users.
The datawind refund department has not cared to refund the amount even after 20 emails spanning over 17 months.There customer care number is not working.

Please do something.
