Capital One Credit Card Complaint

Capital One Credit card department,

APR or interest rate Alabama

I have a Capital One credit card. I paid off my entire monthly balance prior to the due date, yet I was hit with an interest charge. The company said it was practice for interest to be charged unless the card balance was paid off for two consecutive months. It does n't seem appropriate to be charged interest on top of prior principal and interest after the card was paid off during the current cycle.
