Anyone know how to change the billing methods from prepay to postpay, I can't find the edit button in the billing Summary/Preferences.....appreciate your advise!
If you are currently at pre pay advertiser and you want to switch to post-pay (billing at then end of every month), the only way to do this is to close your current account and open a new one with post pay billing. There is no way to switch from pre pay to post pay (and vis versa) in the same account.
