Hongkong & Shanghai Banking Corporation [Hsbc] — Earning Putting Unnecessary Charges

I'm using HSBC card for years I use pay and clear my dues exactly on or before DUE date..

I pay by NEFT mode before 4 o clk or day before due date...I never miss due date but still HSBC charges me like hell...

Even though I pay on due date they taking 3 to 4 days to get credit in card and they are charging me 20, 000 to 30, 000 every time i[censored] call customer care they will tell us to pay the charges and they will not sollve the problem...

Hsbc is earning by looting our hard earned money and putting us in stress...

Today is my due date for my card Rs, 2, 79, 000

I paid Rs, 2, 80, 000 in my card but still they will charge...

I REQUEST HSBC NOT TO CHARGE ME THIS TIME AND PUT ME IN STRESS IN THIS COVID PERIOD..
