Nokia N73
Change speakers for quality sound

I submitted my mobile handset on 30.03.2012 first for change the speakers and servicing at NOKIA CARE in jalpaiguri. They billed me Rs.700.00 (Rs.400.00 for change the speakers and Rs.300.00 for servicing). I paid full amount without any bill (as per their policy). I did not get satisfaction because sound quality was not changed. I further submitted my handset on 05.04.2012. But problem was not solved rather after this time servicing sometimes my handset stop automatically. I live at Dhupguri which is 43 KM from care center at Jalpaiguri and it is impossible to me to easy access off an on.
