They just did a similar scam on me as well. Credit card on online account. Account paid in full. As per their payment site. Called every time they sent a statement for payment due. March 5th 2021 sent a detailed letter to corporate office in U.S. requesting assistance in writing to correct the error. Return address and phone included. Today is March 12, 2021. Waiting for a response... Below is a screenshot of my account. No payment is due.
