Similar query. First time user to pay bills via hdfc billpay platform. Added 2 credit cards. Paid bill after 24 hrs after card validation, 35k and 43k respectively on 4th July, using my visa platinum debit card. Haven't received reward points/ cashback in the redemption section of my debit card. How many days does it take now. The other posts in this thread are little old. And since I've not used billpay before, someone please guide. Thanks
