There are two situations where your due date would not be affected by this change. The first is if you are a pay-in-advance customer, since the due date was already aligned with the start of the service period. The 2nd reason why your due date would not change is if you specifically requested a particular due date. Apparently, Dish sent the notices to everybody, whether you are affected or not. What doesn't make sense, for those of us who are affected by this, is why Dish would automatically change our due date without our permission, only to turn around and tell us that we have the option to pick our own due date. Why not just notify us that we can pick our own due date, and let us decide whether to make a change or leave the due date when it was? That is the way Directv did it.
