Standard Chartered Bank — illegal transfer and it charged

Address:

Bhopal, Madhya Pradesh, 462001

I have two cards withestandard chartered, one platinum and one titanium credit card withe all dues cleared on time so far for start

I would like to lodge an complaint against thee a4 interest amount charged on my platinum credit card on current month statement.

* the a4 interest can only be charged on thee outstanding amount if i have had any outstanding amount due from thee last outstanding amount after last due date. But i will like to let you know that i had paid thee whole outstanding amount before due dates.

On thee both cases i mentioned above from last two months, thee outstanding amount was paid in full within due dates but though there was an a4 interest has been charged on platinum card for this month.

Also i can see that there was an trfd made by bank without my concern from my platinum credit card to titanium credit card on15th nov 2018 which is a day before thee actual due date of outstanding amount on platinum credit card. And titanium credit card

And now bank is charging me interest and gst for this trfd. But i want to clearly mention thee trfd was made before due date and there was no instruction from me to make a trfd. Therefore bank can't charge me any interest on my titanium credit card for making a trfd to platinum card by bank self.

I would also like to mention i have paid all outstanding for both card before due days all thee time and never provided any instruction for fund transfer to one card to another
