FNB IB

I need information on a client of mine that is service by FNB IB - Investor ID 46970. I got a number ***and I have been calling this number for 2 days now holding on everytime close to an hour and to no avail. I got various email addresses to mail them and also all the mails gets returned. How de hell do you do business and the contact details for this department is also not very clear on your website.
