Absolutely no assistance in fixing broken app

I am seriously considering moving moving all my accounts. I can't make 3rd party online purchases, I can't scan to pay because apparently I don't have the correct card, I cant add a virtual card because it just doesn't appear after adding. no one at FNB can help me all I get is emails and phone calls over the past weeks promising that it is getting sorted. 3 weeks now since i have made my last complaint and received no assistance
