Samsung — voice issue.

Address:

Coimbatore, Tamil Nadu

I bought Samsung S5 it's not even 1 year old am facing lots of problem. I given my phone in Samsung authorize service centre for the issue of phone hanging. In service centre they flashed my mobile & upgraded the software but after this there is severe problem in my incoming & outgoing calls. The opposite party can't hear my voice whenever I call them some motor drilling sound is being heard my opposite side party. I recorded the voice & shown to sevice center people but there is no solution I received from. Did I wasted my 38000 rupees buying this Samsung S5 mobile?????? After 2 days am going to lodge a complaint in consumer court if I didn't receive any feedback from u people. Thanks & Regards, Gautam. [protected].
