My prepaid plan expired two days ago and I bought a $15 Top up voucher today. I tried to use it. It said that it was accepted, but there was a problem (i didn't copy the message exactly). Now my balance comes up as zero, but in transaction history it says the top up went through. Any suggestions? I tried calling *611 but they wont let me through because the account expired. And I wrote an email asking for help. But I don't want to pay for help to a problem that is a glitch in the system.
