Western Digital Hard Disk — waiting for Replacement of Hard disk since 1st April 2012

Address:

Thane, Maharashtra

My hard disk of Western Digital had bad sectors (Unable to read and write), which is under warranty till 2014.According to the Western digital, the hard disk is supposed to be replaced within 10 to 15 working days but its more than 36 days since my hard disk is not replaced.The only thing that the western digital customer care executive repeats is that "your case has escalated to the higher authority and within two business working days the harddisk would be replaced". This statement is being repeated since 12th April 2012 but still my hard disk is not been replaced.Due to this everyday atleast one of my family member has to stay at home hoping that the courier person will come and collect the hard disk. This has caused lot of trouble for me and my family it's like a house arrest for us.
Still they are saying the same thing again and again which is the more frustrating part.
Details of Hard disk is RMA(Request no.) = 83533389,
Please help me to get justice , I am really very frustrated with Western digital company they don't care at all for the customers.
Hoping my problem would get resolved soon.

Thanks
Tarun
