FNB Incompetence

I had lodge a complain with FNB in January when I send an ewallet to my friend and we find out that his number has zero account and that account doesn't belongs to him. I send money using zero account form myside, and unfortunately money send from zero account is that I cannot reverse it. FNB come back to me when I complain to them telling me that they're still investigating. I mean three months investigating? Because I want to know if I am getting this money or not, they're so annoying and so unprofessional.
