Just to be clear...what exactly is a payment extension? My first thought is that you need some extra time to make your monthly payment. If that is so then just call Exede and explain the situation to them.
Virginia, you will need to call 855-463-9333 to discuss your account. We can't do that here because this is a public forum and, not a direct way to contact Exede/Viasat so, give them a call and ask for Billing and Payments. They can help you.
