Since we have the bond with Fnb we had problems

Since we have the bond with Fnb we had problems. Issues with over payments that went into flexi/access bond which disappeared and I have been given all sorts of incorrect answers as to where my funds disappeared to. Furthermore we never have a proper answer up until today and need answers . I received 3 different answers via email stating the disappearance of the funds then my email account was hacked and to my surprise the 3 mails was deleted and removed from my account therefore I need a contact from their IT department to see who hacked my account and where the funds disappeared to. I sent several mails to enquire what my monthly bond repayment is but still no response. I have more related issues such as Insurance etc.
