Add Rs5 on mobikwik wallet using Axis RuPay CC and saved your card as token and try, Hope it will work.
Anyways its bank and mobikwik issue. contact mobikwik customer care on twitter.
There is no link between credit card bill repayment and card networks.
It works on banks own internal network via IMPS/NEFT/UPI/BBPS/RTGS etc.
