I just checked the status of my payment request at World Bux and the status was Payment Denied. I’m not sure what that means, as it wasn’t one of the listed possible statuses, so I’ve submitted a support ticket.
It could have been a problem with my AlertPay email. I tried removing the email I was using from my existing account, in order to use it to open a business account. There were a number of problems when I tried to do that (it wasn’t recognizing the fact that the email had been removed, so wouldn’t let me use it to open a new account) or because my account is unverified. I’ll see what the response is.
