Lenovo — Lenovo K5 plus faulty piece/ handset

Address:

380050

Ordered a brand new piece of lenovo k5 plus in february 2017 and recieved just to find after some days that there is a network problem with the device. The network is available only when outside my home or office. Dissapears as soon as i come inside my home, office or any other closed building.
Just one month on and the hand set went wrong... Recieved a faulty piece from flipkart.
Recently given in lenovo service centre since 10 days and they told that they need to change the motherboard of handset.
