Sony Music System Z100 — Poor after sales service

Address:

West Bengal

I purchased one Sony Z100 5 CD changer music system at around Rs.30,000/- some few years ago. However, the system got conked and it was not working. I gave the set to Sony Service Centre for repair. However, they failed to repair the set which is quite surprising to me. It was not that old and obviously and surely customers like me want that Sony Service Centre should repair my set. I am helpless and have to discard this set just for a small repair. Maybe a small part went wrong for which surely Sony Service should support and provide the part to set right my costly set. Please advise me where can I contact for remedy.

Thanks
