Make sure, you pay the minimum balance. Refunds will not be considered as a payment if bill is generated.
Again that is debatable and different bank follows different strategies. We have heard in this forum where interest was charged by probably AXIS or SBI Bank (Don’t quite remember the bank).
In worst case scenario where you dont want to pay and still get charged interest, you can connect with customer care and request for refund of interest, but thats a unwanted tiresome procedure, Better to pay minimum balance and keep it simple.
