If you didn't in the past have to have the authorized person available to talk to on the phone, and that's what you are referring to, it's most likely that they, Hughesnet, have put further steps in place to protect the account holder.
As to why you would have to do so again after you were supposed to have been added as an authorized person during the previous call, I have no idea. I suppose it's possible that they will ALWAYS require the original account owner to be present when changing anything on the account. Not necessarily when calling about an issue, but when they need to alter something on the account that can affect the original account holder.
Though very frustrating, I'm sure, and again, I can't answer why you had to go through the same thing again, it's evident that they are VERY proactive in protecting the account holder. That, at least, bar the frustration, is something to commend, as some comapanies aren't so vigilant.
At least, in the end, you were able to get the account reactivated (or I hope so). :)
