Consumer Redressal

Sir,I had purchased one MTS Mobile(Model MTS DUET ZTE-N790) from Vivek Distributors on 10 May 2013 by paying Rs.5,400/-with one year warranty.The phone was having touch screen problem in the initial months itself.Later it was found complete dead.I took to the service center on 6-5-2014 at Nagasree communications,Mangalore.They promised one weeks time to repair the hand set.But till now I have not received any positive reply from the center.I lost all the calls in that number since the SIM is not compatible for any other hand set.So I request your honor to get my amount refunded to buy another good hand set having service back up
