RBI has changed some rules regarding subscription payments using credit cards and none of the payment gateways are accepting any credit cards currently. This may take some time as the banks need to upgrade their system to provide additional factor of authentication.
Here is our interim solution.
If you have UPI Id, you can pay to 9823013693 or to indianraga@ybl. This is registered in the name our Director.
Alternately if you want we can share the bank account details with you for transfer through net banking.
You need to remember the date and make the payment after every 4 classes. We will switch you to proper system once the issue is resolved.
