Sony India — Repair of audio system

I had deposited a audio ( Model no.CFD-RS60CP/CSP5) as on 23.08.2014. for repair as per job no. J42220964 as on 23.08.14. But I am sorry to say, after a gap of almost three month, I have not get the required service from your end. It is necessary to mention that I have already paid the required service charges. Sony is a world wide reputed brand. This is unfortunate to me as a customer, that the trust of the brand is decaying. Please see the matter and solve my problem as early as possible.
