I paid a couple of low value CC bills last month - by using HDFC Visa Platinum DC - NO 1% CASBACK REWARD POINTS CREDITED TILL NOW.
But, got 1% CASHBACK Reward Points
when paid similar low value CC bills - by using HDFC BILLPAY and by using AUTO PAY ENABLED.
So, if we pay CC bills by using HDFC's DC on 3rd party Apps, we may NOT GET 1% CASHBACK.
But, if we add billers to HDFC BILLPAY and ENABLE AUTOPAY of those added billers, we would get 1% CB.
It's my observation after experimenting with many alternatives n options.
Hopefully, it lasts....
