HDFC Bank — Did Not meet the promise they met at the time of issuing the card

Address:

Bangalore, Karnataka

I am having Titanium Times Credit Card. While issuing the card, they told me i can use the reward points to pay the credit card bills. Now They are saying this feature is not available on this card. If consumer doesnot pay bills in time, he loses his CIBIL score. Should this not be applied to bank also? If banks mis-communicate to its consumers, they should lose some kind of score which has to be made public to stop this kind of fraud. Can someone guide me how to handle this?
