AXIS BANK – UNAUTHORIZED TIPS/SCG/NONMCC – ONLINE PAYMENT

I have recharged metro card from metro AVM by using Axis band credit card.
After two day. I have received message from Axisbank regarding this TIPS/SCG/NONMCC charge
During whole process they have not provided any information regarding surcharge. Why they are debited money after two days.
My money is not too much but still they debited money from our account for any relevant surcharge
