RMB PB and FNB Easy Zero back at it once again.

The fact that I cannot transfer money between my RMB PB account and my Easy Zero is frustrating me, giving me an error about "System currently unavailable", which doesn't make sense. And none of the RMB people can help or even the easy zero. I need to access the funds immediately. I have spent time over the telephone with them transferring me everywhere but they have no help. Even the chat on the app was fruitless
