Cutting off current customers from abroad

I emigrated with the idea to fully financially emigrate a bit later when I am ready. I never thought I would be blocked from entering my own account with an overseas IP address. Let alone the whole website. I have no way of logging into my account and/or checking the worth of the fund in which my money is invested. I have corresponded with Coronation various times to unlock my account until I came to learn what the reason is for blocking me. Then I asked to unblock it once again so that my sister can login on my behalf to help me out to make an informed decision but we were still unable to login. I only receive the quarterly statements to know where I stand. Because of the time difference between countries and the cut off times of Coronation to sell I have no way of making an informed decision. This is beyond ridiculous that I can't manage my own money from abroad. I am frustrated and am forced to leave my investment until I visit SA again or to sell without even knowing if it is a good time to sell or not. Apart from that it seems like the fund I invested in is doing very poorly the last few years and it is supposed to be a top fund at Coronation
