Majorly paying credit card bills using rupay cc upi is not allowed anywhere. You can use Mobikwik to pay credit card bills using other credit cards but they charge a fee of about 3%.

You can make payments to merchants using the Rupay CC (I do that regularly - have HDFC Rupay card), but not to other credit cards, this is not allowed under RBI hence none of the banks can even offer it as a service or facility
