Lenovo — Regarding my lenovo k4 note phone...

Address:	110092
Website:	NA LENOVO

I submitted my lenovo k4 note phone to lenovo service center shakarpur new delhi on 8th of july. My complain was that wifi, bluetooth and hotspot none was working any how. Other wise my phone was perfect.
Representative submitted my phone and asked to come on 10th of july.
When i went for my phone to center on 10th of july. She said that will need to change mother board which will cost 7000 approx.
I refused for that service and asked to return my phone. I found that my phone is switched off. I asked rep to switch on the phone. After some time rep said that phone got dead and cannot do anything now.

I do not understand that what type of service is this. Really very disappointed.
Please do something and sort out my problem.
