I can understand why all banks are targeting the utility payment category, but this is totally unfair for common credit card users. Banks can implement some capping on the maximum reward points one customer can earn from the utility category rather than totally excluding it. The bank must not forget that utility is a very essential category; everyone spends some money on utility every month. I don't think this move is a good idea. However, it's the bank's decision, but you can also close your Axis Vistara cards and move to SBI Vistara or IDFC First Vistara Credit Card.
