Impossible to migrate to Fusion

I have been trying for hours to get help from FNB and nobody has been able to give me any assistance with two issues: 1) I am unable to make successful contact with the call centre. 2) My request to upgrade to a Fusion account was declined. 1) When calling any of the call centre numbers listed on the FNB app (both through the app and outside it), the call cuts and I am not put through. After typing in my ID number and # and then authenticating through my app, the automated voice tells me that I have been successfully authenticated but then cuts the call. This has happened over and over. 2) I cannot apply for a Fusion account on the app (the message ‘system unavailable’ pops up every time I try). My wife got a call centre agent to call me and he helped me apply over the phone. He said that the application was declined but could not tell me why. I have since been transferred to many different departments and nobody can tell me why I was refused or what to do next. Can somebody PLEASE help resolve these two issues? I am now at my wits’ end!
