i bought Sony LCD TV worth Rs 21777 from ebay and i applied for the Diwali Gift of WD external HDD, as per Ebay T&C Hdd will courier me within 45 days but i get it after 90 days.
And main thing is they are give me THOSHIBA HDD in place of WD when i Call to Ebay CC they replied both are same but practically see
WD is more faster then Thosiba
WD is Reputed brand in External HDD compair to Thosiba
WD is costly item, and many more..
Thosiba having very poor performance, Poor body plastic, even plug of Wire.. so how can i accept this product compair to good one

another thing they are not mail me for that and Directly send item
E.g.
If i buy nokia phone from ebay and they give me NAKIA Mobile, is there it is fair or not, or they give me another company mobile with same feature then it is fair or not.
