Decided to move my wife's phone to pay monthly because of the new $29 plans and 100 bonus minutes. That didn't take long - maybe 5 minutes. But once I did it I discovered I had forgotten to apply all her top up vouchers to the account and 2D customer support said I couldn't use them once the phone was on a monthly plan.

So the only way to do that is to move the phone back to prepay but there is no option for doing that online which is strange. You have to talk to customer support and even then it is going to take (as I write this about 30 minutes after switching) 2-3 hours apparently.  What's wrong with their system? If they are integrated enough to do online credit checking etc, you would think the simple act of moving off pay monthly would be easy to execute.
