My datawind ubislate c was purchased in may. Only after few days of receiving the product, It stopped charging and even if i do not use it, It was getting discharged. After a long effort i could contact the customer care to know about the service centre in kolkata, I. E, Phoenix international, And on th August with job card number Lkascwbj. Even after almost months over, I am not getting my product from the service centre. They are telling that, They have sent it to the head office. How long datawind will hold the product the whole warranty period i am really repenting on my decision of purchasing the tablet from datawind.
