Contrary to the experience on SBI Unipay reported here, my experience with it is good so far. I have so far paid around 10+ CC bills in March & April and all have went through and got credited successfully without any issues. I have paid for Amex, HDFC, ICICI, AU, Axis, BOB, IDFC credit card bills. I have always used Rupay CC (BOB Easy / IDFC / ICICI Coral) as the payment source and the bill amount varied from 1000 to 20000. [To pay the Rupay CC used as payment source, I use HDFC Bill pay with Platinum DC].
