Luno can tell what's (apparently) wrong, but not how to fix it.

I am trying to send eth from Luno to a large international exchange and keep getting the same error code only to get told I am doing it wrong without getting told how to do it right (also not my first time doing this.)

Seems more like purposeful blocking than anything else.

As soon as I figure this out, I will make sure to never use this platform again. So much easier with large international companies
