JPMorgan Chase & Co. Credit Card Complaint

JPMorgan Chase & Co. Credit card department,

APR or interest rate Texas

To whom this might concern, I am writing to complaint about Chase credit card fee management. Chase has violated the customer agreement when they keep charging the interest fee on the TOTAL PURCHASE of the month instead of the outstanding balance after I made the payments. For example, I purchased $4000.00, paid $3000.00, and am subjected to the interest charge on $1000.00. Chase charges the interest on my entire $4000.00 purchase for the periods for multiple months. I have attached my statements that show how Chase calculates the interest on the total monthly purchases. After multiple attempts contacting Chase 's customer services, the issue has not been resolved. I have closed the account. I would like to file the complaint against Chase practices since they originally violates their agreement, falsely charged their customer, failed to resolve problem, and made no further attempt. Thanks and have a good day! Sincerely,
