[Resolved]  Fly Mobile Model No. V110 — Mobile not served properly

I bought Fly Mobile Model No V110 six months back. The problem with the mobile is that when i am trying to listen FM it connects to calls and trying to load songs it shows that the battery is charging. I had taken up this matter to authorised service center but i havent got any positive help from the service centre. They kept the mobile with them for almost two months and keep me roaming here and there as the authorised service centre is at andheri kurla road. So please help me how to get my mobile servicable
