Kotak Mahindra Bank — credit card issue

This is very pathetic service from kotak credit card department. As i have paid the billing amount on 3rd jan 2019 and my last date of payment was 5jan (There is some neft issue with bank and payment will reflect to kotak on 9th jan. Now i have received the new statement on 18th of jan 2019 and found late fee charges added with interest and gst in my current bill.
Why i need to pay late fee charges?
