[Resolved]  Western Digital / Hdd — replacement not done

hi i am vivek gupta, i purchased an external hard disk of western digital company in the month of january last year and within few days it stopped recognizing the computer. i called the support centre and they gave me a rma no[protected], complaint no- wd[protected], hdd ser no- wx90ac9r4927. they sent me replacement but without rectification. i called them back and again they told me to send the hard disk saying that they would replace it back. i had it sent to them in the month of may and since then have not got a replacement. i have mailed them several times, called them also but they just make false promises and nothing is done. the next time they gave me different rma no tht was 81993078 complaint No wd[protected]. serial No WX90AA964767.
