Non Compliance of described facilities and actual for Privileged Membership

I was told 25% discounts on all purchases on the additional card towards holding SBI Credit card for long time over telephone by Mr. Neeraj, Sr. Executive, Cache Mercantile. But, while going through the details sent by them it is not complying with their words. It is purely for hotel and food section only but while describing, they told even I can avail 25% discount at Bigbazaar also. They called me on 04.07.2012 and told the voice recorded will be given for verification in future also but now they are denying to provide the same.
