Hi David, I am so sorry you are having issues with our billing. Please send your account and contact information to firstname.lastname@example.org and we will work with you one on one to figure this out. Thanks.
I can see that happening if you made a manual payment close to the due date, then the computer at Viasat took the automatic one too. No need to make a payment manually, just have the funds there and wait for the automatic one to happen.
