Sony India — Worst quality and service from sony mobile

Address:

Jamnagar, Gujarat, 361001

I have purchased sony experia aqua m4 dual for rs. 19000 on 27.07.2015.
My mobile got automatically locked in first week after purchase and had to submit it to service center.
After receipt o[censored]nlocked phone found that speaker and microphone was not working. Again 2’nd time submitted to service center and in return i got defective refurbished phone and found that dead pixels on screen.
Again 3’rd time submitted to service center and in return again i got defective refurbished phone and found dead pixels on screen at different location.
Now 4’th time i have submitted the phone on 27 april 2016 but i have not received the phone yet.
Most of the time my phone is staying at service center since purchased and i am not able to use it, so i have raised request of refund or replacement with new seal pack device instead of refurbished phone. But till now no resolution received. They are lingering me and wasting my time. This is how sony is treating / harassing their customers.
Person from customer care is replying that i will get new sealed packed phone but service center is denying for the same. Till date no resolution is received. Please do needful.
