Hello sir maam
I purchased the above, in 2009 from casa madhav panjim. It was repaired in 2016 by self at mumbai. Since it's a sony product, i didn't want to throw it so i tried calling sony company in feb 19. The company willingly said it can be repaired so i told them to go ahead, it was repaired for rs. 3000/when i received the item it played for 10 minutes, i called up sony call center and send email, with lots of personal request. They took it back second time and took rs. 236/ for transit, it played for 45 minutes and then again same defect, now i am fed up with it, i wanted my money back, but they are not entertaining and saying that the instrument is very old. My question is that this they could have told me it cannot be repaired, so that i could get it replaced. Now i don't know what to do, kindly advise how to get my item repaired or my money back i am also going transfer from mumbai on 12 mar. 19. Regards
