Diners club rewardz is a credit card for the customers Who need discounts and reward points on dining swipes . When I got my first credit card which is diners club rewards on last January 2017 I thought it could be used everywhere . The next month I went for a shopping in Big Bazaar where I purchased clothes for me and parents . For paying I used my credit card. Surprisingly it was not working . I thought that might be some error with the swiping machine so I told them to sleep again . But it was not working . At last I paid with my ATM card . Then when I went to HDFC Bank asking what happened to my credit card the same sales executive who pitched me saying this is the best friend card from HDFC, said that it cannot be used for shopping . I was shocked . If a credit card cannot be used for shopping then what it is for . He said it’s only usable for swipe in in restaurant dining and booking online tickets and a serving seats in star hotels . He says you will get double reward points . But a card which cannot be used elsewhere is the worst . I don’t understand why they have launch this kind of credit cards . The same day I send the request form to cancel the credit card and a personally said to the sales executive note to sell this kind of credit cards to any customer saying this is the best card only for achieving their sales target .
