As a follow up, my existing US data/talk bundle which was at 00/15 was removed and I was able to apply the funds to a new plan. I'm not sure if the moderators removed the old plan or it just passed 12:00AM ET so it was removed as expected. In either...
I'm having the same issue. I've paid for a US text/talk/data bundle and it won't load into my account. At least it doesn't use up the funds but I am unable to add the plan to call home. I've filed a request with the moderators.
