About an hour ago I went into their flagship store to get a $10 prepaid card, they first asked me what network I was on, so I told them XT. They explained to me that I was only able to buy $20+ cards on XT, and despite my disagreement they threatened that they would "Lose their job" if they sold me a $10 card to an XT customer.
I then just said, "Well lets pretend I'm on your CDMA network, it won't matter because the prepaid cards work the same" but she told me no, because I just said I'm on XT.
So I left and went to the dairy and bought a $10 card which worked as it should.
