Nokia India — Software Problem But _ Nokia care guys saying It is a Hardware ISSUE

Address:

Bangalore, Karnataka

I have a problem with my NOKIA LUMIA 520, In that mic, speaker, earspeaker is not working, Cann't able to switch to LoudSpeaker when calling. When I try to take photos its working fine, but when I try to take video camera app automatically closed, similarly some third party app which downloaded from Store like Voice Record Pro, , , also having the same problem (Automatically getting exit). I went to NOKIA SERVICE CENTER (Address: 80 Feet, 2nd Floor, CMH Road, Beside. ICICI Bank, NGEF Ln, Indira Nagar III Stage, Binnamangala, Stage 2, Indiranagar, Bengaluru, Karnataka 560047 Phone:[protected] These guys saying that its a hardware issue, But I will bet that is not a hardware issue, its a software issue, When I ask them to do something, they are saying some unrelated( hardware )problem. They took Rs.100/- for Inspection, Waste of Money & Waste of time.
