HDFC Easy shop Platinum DC


KF Ace
I have HDFC Easy Shop Platinum DC in which there is Rs 750 Cashback P.M . I have to spend 75K through DC it's not possible to pay bills and recharge of 75K now there is an option to pay credit card bill in HDFC Bill Pay but HDFC Credit card is not available there as I don't have any other credit card without HDFC can anyone tell me why can I get this cashback.
750 is the max cashback you can even if you spend like 50k through your Debit Card you will get Rs 500 as cashback. Apart from paying credit card will you can also use it for normal online or offline transactions to get the cashback benefit
