FYI, resolved the payment issue. Turns out the post office recently changed the name of my street address, so the address verification failed on voipos refill process. I just had to update voipo and my credit card company so everything matched.

Anyway, having reseller accounts lock out is just not acceptible. I'm happy to prepay, but let's get the refill threshold set somewhere other than $0... preferrably a reseller selectable amount, but at least $50 or something, so resellers have time to figure out why a refill didn't work before their accounts turn off.

This was a bad morning.
