The agents who market these cards doesnt explain all these things while marketing, wooing the customer to take the card. They simply say life time card, Interest from the due date over, Interest Free period for 45 days ( depends on the bank). The customer is not given time to read all the points in agreement while signing the papers(except for a few). They simply say Ineed ID adress proof, photo and few signatures. the customer will comply as if he doesnt want loose the opportunity be a card holder. The problem starts when we receive the bills.
