Samsung Hard Disk — read and write defect

I bought a Samsung disk from your dealer about three years back with a warranty of 5 years.
The details of disk is: capacity-80 GB, and number is SP0802N, P/N 0821J1FXB09143

This is to inform you that this disk has developed defects, the details of defects are as follows:

1. The hard disk is not working, neither its reading nor writing, It happened all of a sudden and I could not get the backup too.
2. The plastic on its back mounting the cable connector is made from the material of a very low grade quality that it is cracked by it self, although this defect is not responsible for its read and write defect.

I am submitting this complaint with the sealed hard disk to you for replacement, as its warranty expires in Nov. 2009. Therefore I shall request you to please replace the hard disk

refused replacement by meerut service center

Dealer said he has about a half doz hard disk but SAMSUNG is so Bad that they don't replace
