JPMorgan Chase Credit Card Complaint

JPMorgan Chase Credit card department,

APR or interest rate New York

I have a Chase credit card with a few zero percent balances on it. They have not been crediting my payments to the balance with the soonest end date for the zero percent offer. On inquiring with them, I discovered that their policy is to credit payments to the balance ending first until the soonest ending balance is withing 60 days of ending. I believe that the balance ending soonest should be treated as the highest interest balance and be credited first. Their policy is in no way clearly stated.
