I have had the same problem with 'grayed out chat lines' for several days.
I am in remote area of Baja Sur Mexico, with phone suspended, but I am continuing to get billed via my auto pay account at my bank. I can't call 800 numbers from my Mexican phone. ¿Cuáles son mis opciones? I can pay several months in advance (had suspended for three months, but just activated today to be able to re-suspend for additional time), but don't want the hassle of trying to get a refund when I return . . .
I can't figure out why I am getting billed at all, plus my account shows much higher billing for both accounts than what I should be paying . . . absurd!!!
