Capital One Credit Card Complaint

Capital One Credit card department,

Transaction issue Texas

I always pay my balances in full. I went online to pay my account balance two days over due. I checked the box that said pay last statement 's balance which was $740.00. To this balance they added the charges for - that had not yet come due totaling $1600.00. When I questioned them about it they said the payment was being processed, and there was nothing they could do about it.
