Did you read this conditions when you applied?? Just wondering. And NO I do not work for them

Did you pay by the due date shown on your monthly statements? Why did you disregard the late payment penalty noted on each statement for the previous month?

$39 a month for 12 months equals $468 so why do you claim they are charging you an additional $1300?
