Consumer Redressal

This is regarding my purchase of Mobile Lenovo - S660 from Shop J.K.Electronics NX - Thane (Cash Memo:15363/JKE/2014-2015). Purchase on 24.02.2015. This is to inform you that from the date of purchase the Functioning of Mobile are Very pathetic. Its very difficult me now to handle this mobile as it hangs and Switch-off the entire system of mobile time to time. I Given it in Service Center for servicing and collected from them but same problem arise again and again. i am very much disappointed for this phone. I contacted Lenovo on following Email Id's: smartphonets@lenovo.com, support@lenovoreg.com, Lencare@lenovo.com, services_ed@lenovo.com But didant get favorable reply. They say give the Mobile in Service Center again for repair to serve you as they say its an touchpad problem but they replace it before then also same problem arise. Now i dont feel so. Please take my Complaint into consideration and do the Needful. Waiting for Your Best Reply. Regards, Raunak Khan
