Thanks @AskCapitalOne for resolving the issue today and refunding the interest after a long back-and-forth. I appreciate the supervisor who finally helped me out. Hoping the team reflects on how to streamline this process for other customers.
@AskCapitalOne Charged unexplained interest on my Venture card despite paying in full. Was on with a U.S.-based rep, escalated—and got hung up on. Please escalate this to someone who can actually fix it.
