The statement says that you've triggered the Penalty APR so that it has now increased to 28.99%. What action  triggered this?

You failed to pay the minimum payment by the due date.

Explanation:

The Penalty APR is triggered when a cardholder pays late.  The credit card issuer will assume the additional risk that may result if the cardholder fails to pay at all.  The purposes of Penalty APRs are to offset the high credit risks involved and to encourage cardholders to make their payments on time.  This also why APRs are usually high.  Lenders or credit card issuers then charge high interest rates to compensate for the risks.
