I have purchased sony davtz130 model home theater system in 2012 at rs. 10000.00. From last week it stopped working and i handov3er the same to sony authorised servicing center at tezpur. After submitting next day one representitive from the authorised servicing center call to and advised me to submit rs. 9500 approx to repair the same. Next day he send me the quotation of the said amount. Then i send a mail to sony portal contract us portal but no reoly has come till now. Now my question is 'is it a true quotation which involves the same amount to its cost price was in 2012" and if so then what is the use to purchase a sony product. Please look into the matter...
