I get the feeling you might be some sort of PEP or have a criminal record related to finance in your country of origin, it's incredibly suspicious the amount of thorough information they asked you, in my experience it was much MUCH simpler than that and I can withdraw the totality of my funds at any time (I actually did early in January - no issue at all)

So, IDK, I feel you're conveniently leaving out some info, maybe its the paranoid in me talking but, that's just my thoughts.
