I hear ya Gabe.
The only real issue I have had with Hughesnet in over 12 years was billing related. It took ECC to get it resolved so the Billing Department holds a special place in m heart.
If I found myself unable to process one-time only direct debit payments I would likely end my Hughes service and go with the poor DSL Frontier service that is available.
It was my personal experience that having banking.credit info on file or giving out that data over the phone leads to a very difficult situation.
That is my point of concern over not being able to process an advance payment under the "new and improved" pay site.
