[Resolved]  Toshiba Led Tv — Voice not received in led model no - 32p2305ze after 3 (Three) days of purchase

I purchased new led toshiba model no- 32p2305ze, serial no- eox14h01067k1 on 09/03/2014 from sony music, jamnagar. After 3 (Three) days use, voice problems occurred and not received voice. So i complained to toshiba by complain no- sr3f0023556 and mobile no- [protected] on 15/03/2014. The mechanical visited and shown some part problem so it must be replace immediately. But after 7(Seven) days, my complain is not solved and it is not good for any international company so, please, solve my above complain immediately as possible.
