Samsung 80gb Hard Disc — delay in replacing hard drive

Address:

Mumbai City, Maharashtra

i have bought a 80 gb id hod in the month of december 2009 it was not performing well and i found it out that it has got some manufacturing defect as it stopped functioning so i returned it to the setrvice centre on 5 th of march 2010. it is a new hod with manufacturing defect which was identified by service centre still not replaced by the company and whenever i call to service station they tell us company has not provided disc yet so we cant replace it. at the same time we are loosing our valuable time and money we have lost already behind a defective brand new hard disc.
