Address:

Hello sir I am Santosh I have used to SBI Simply Save credit card. My Mobile no [protected]. I was paid credit card bill in month of Nov. 2015 in which i was paid short amount . my credit card bill was Rs.26101.39 and i was paid Rs. 26050 only (short payment of Rs. 53.39). Bank has charged interest on total Amount Rs. 26101.39. And i contact to bank executive he told me thats my policy and you will pay finance charged on total amount not a short payment but i thinks this is wrong policy of bank.
