Discover Credit Card Complaint

Discover Credit card department,

APR or interest rate Nevada

I have set up for automatic payments with discover card. They have only withdrawn the amount due on the - instead of the -. ( I have called them many times to correct this and finally today they have properly correct it ). As a result since at least 2009, I have been charged numerous late fees as well as penalty APRS of up to 27 % as a result. Ive asked them to correct the penalty aprs as well as late fees incorrectly charged and they said its too long ago and they can not correct it!!
