Consumer Redressal

Hello Datawind, I purchased on Ubislate 7CZ on 2, March 2015 with Invoice number : TILD 030200123. It arrived me on 7th March via Blue dart. Then due to some software issues I had to visit your service centre in Kolkata, Mobi Care on 12th MArch 2015, Work Order Number : RVSRN1503LMB00069. Then after couple of days they said that as my set was recived within 7 days of delivery, with the help of service centre I can claim a replacement. I did so and they ordered for a DOA which was approved from your head office. Now it's more than a month I have not received my set yet, whenever I call the call centre they say that it's under process. This is completely unacceptable. Please do the needful and send me my set or I need a moneyback. Thanks, Kushal Ghosh 9830228729 Kolkata
