is there any way to recharge FASTAG without any charges via cc

I used Park+ for Rs. 500 recharge of my fasttag and payment method as CRED.

In Cred I used credit card. No additional charges.

Amazon pay

You can use mobikwik for upto 2500₹ recharge.

Post that they will levy some charges.

You can use multiple mobikwik accounts with same CC

Cred pay, Tata Neu . They get credited instantly as well. Before these apps, I used to recharge directly in AXIS fastag portal using cc WO any charges. 

payzap also without any charge

I recharged by Axis Fastag from Billpay section in Tata Neu and used my Neu credit card without any additional charges.
