Citibank Credit Card Complaint

Citibank Credit card department,

APR or interest rate Pennsylvania

Citibank is charging " residual interest '' on a statement from - days go when the entire balance was paid in full. I paid $750.00 in -/-/- to bring the account to a - balance when the account statement was for $720.00. In -/-/- they billed me $24.00 in interest when I paid the previous statement in full. When contacted they said it was " residual interest '' from the -/-/- statement when I paid $500.00 and the bill was $550.00. I paid $4.00 of interest on the remaining $57.00 in -/-/-. I attached -/-/- 's bill to show that every month my bill was paid in full and the account was always brought to a - balance. It is illegal to charge " residual interest '' after you show a new balance & continue to accrue interest on an account. The final balance is always to reflect all money owed on an account except for outstanding charges not finalized by a retailer since the bill was cut.
