Hello
@SlyMOnly ship to home orders are able to charge it on the bill. You have a pick that way. Upfront via CC or bill. As long as your account is up to date and u don't have a u past suspensions on the account.
As I said before. It was for selected store trial. My store was one of them.. In February of 2017 is when they started rolling it out to all stores. Again all carrier stores are doing this because many don't end up either paying their bills on time and let the device balance pilling up so it ends up going to collections. Also it's easier for some customers to pay upfront at one instead of waiting for the bill to come..
If you can't pay it on Friday then I guess you will have to wait to upgrade at another time. The stores can't reverse this either. The system won't allow the upgrade to go through even if they tried.
Best Buy is doing the same as well.
