Sansa Sandisk MP3 Player service centre in pune

Hello All,
Recently i purchased a Sandisk Sansa E270 MP3 Player thru this enclave and for some reason i need to repair it as its earphone socket has lose connection,
I do not want to get it repaired from any ordinary shop,

please let me know if anybody knows about a service centre

P.S. Even if it is not Sansa shop but someone who has expertise and reliable should work.

Thanks
