I HAD GIVEN MY PASSION PRO(DL 13SJ3111) ON 27-04-2011 AT 7.30 A.M IN THE SERVICE CENTRE.AND THEY GIVE ME AT 11A.M. WHEN I INSPECT MY BIKE I FOUND SOME PROBLEMS IN MY BIKE WHICH SHOULD BE DONE AT TIME OF SERVICE. IT IS IN GUARANTEE PERIOD. THE CHAIN SET IS CREATING A LOT OF NOISE BUT IT WAS NOT CREATING NOISE BEFORE. WHEN I TOLD THEM THAT THE CHAIN SET IS CREATING NOISE THEY SAID THAT (YOU RUN IT 4 OR 5 K.M. THEN THE NOISE WOULD BE STOP. BUT THEY TOLD LIE THEY HAD REPLACE PART OR THERE HAD BEEN A MAJOR DEFECT IN THERE SERVICE TIME. I WAS CHEATED BY THEM.
