Motorola Mobility — Since last three months complaining about poor mobile network receiving

Since last three months complaining about poor performance of your Moto 2G instrument which I bought through flipkart. Thrice serviced by your recommended service center at Erode 638012 which also failed. The issue is sim port which is not supporting signal receiving while in remote place where other ordinary mobiles are able to catch the signals. I have samsung, nokia, micromax which are all able to get the network where as yours is attire failure. I logged complaint thrice no improvement at all. Let me have any suggestion from your side. IME no of the mobile : [protected] & 372. Murugan, [protected] Erode / Tamil nadu.
