My credit card charged me interest but according to the statement I should not have paid interest. See below : Per my statement below is how the interest should be charged : Avoiding Interest on Purchases ( Grace Period ) : If you have both Purchase balances with an APR greater than 0 % and you also have other promotional balances on your Account, you can avoid paying interest on your Purchases by paying {$4700.00} ( this amount includes any Minimum Payment Due required to avoid a late fee ). Please refer to the " Accrual of Interest and How to Avoid Paying Interest on Purchases '' paragraph on the back of this Statement for further detail. 
Per the back of my statement as reference above : B. If you have Purchase balances with an APR that is greater than 0 %, and you also have other types of promotional balances on your account, you still may be able to avoid paying interest on those balances without paying your Statement Balance in full. If this applies to your Account, you will see a Paragraph titled " Avoiding Interest on Purchases ( Grace Period ) '' appearing directly below the Interest Charge Calculation section on the front of this Statement. This will show the amount you can pay by the Payment Due Date and still avoid interest charges on your Purchase balances. 

I followed these terms and paid the amount in full by the due date of XXXX/XXXX/15 but they still charged me {$65.00} interest. Their response to my inquiry was that since the balance was for a promotional offer that ended on XXXX/XXXX/15, there is no grace period and interest started accruing on XXXX/XXXX/15. If that is the case it should be clearly identified as due XXXX/XXXX/15 to avoid interest on the statement. The statement is misleading at best and they should not print this on the statement if it is incorrect. Had I known there was no grace period I would have paid by XXXX/XXXX/15.
