Lenovo — defected mobile set lenovo 526 not working properly

Address:

Bardhaman, West Bengal

sir, I have purchased Lenovo model no 526 in Aug. 2014, in starting time my handset is hanged again and again. I consulted ur Sercice Centre (Diurgapur, W.B) branch in October 2014. it is formated set but my problem is not solved. Last two month it is seen that the tower of network is fluctuate some hence call drops is happened and battery is also lapsed half a day. I consulted ur service centre again ur service centre on 4/4/2015 it is said that mother board may worst, after replacement of motherboard my problem is still now. I am very frustrated about set. I consult ur toll free no yesterday and handover again ur service centre that is changed in three time in last 6 months . Hence pl. look into my case and resolve my problem. thanking your Manoj kr Morya
