ICICI Bank — ICICI CREDIT CARD looting me

I already paid all the amounts on time . but due to 3rd party bill payer take little time to reach that last 303rs amount to credit.
for 303 rupees, ICICI charged 4737.07+852.67, Totally 5589.74 rupees..

This is against their terms and conditions, also injustice to me.

303 is not equivalent to 5589rs just for 3 days delay...

I'm a 9 year old ICICI ACCOUNT holder. now i think to revise my decision.. never wants back.

I want my money back.

please take necessary actions
