Another update:
I dialled HDFC/AXIS CC Customer Care numbers, and they confirmed to me that there were a few refunds that happened on my credit cards for some transactions, which I did after Statement generation date but received the refund due to some other reasons which is calculated as paid amount strangely but it shouldn't be. They acknowledged the issue & registered one ticket for it which is being taken care by their IT team to fix this calculation anamoly. Customer Care officer advised me to pay through NEFT & I did it. They shall adjust the amount accordingly.
For SBICARD CC, surprisingly there was no refund or nothing. I hardly use this credit card & I transacted last time during Amazon Freedom Sale (15th August). Still it is not allowing me to pay the same amount via BBPS or BillPay gateway. I tried to reach Customer Care to understand the anamoly but I didn't find the existence, line is continuously busy. I have already emailed them the issue. SBICARD is allowing me to pay less than 60% amount of actual statement due. I shall update here accordingly but this is a scam indeed. I tried to pay the maximum amount via CRED, now it is showing as 'fully paid'. If bank is allowing 50-60% of actual statement & CRED or any other app is showing that less amount as fully paid, definitely it's a SCAM. Why bank is allowing me to pay 50-60%, I didn't find the reason for SBICARD also how can a refund of a transaction which happened post billing date, calculated as paid amount, this is also pretty surprising!!
