I am fed up

I have been requesting for assistance with my banking app, consultants from the branch in Soshanguve Crossing keep on refering me to their call centre of which I hold for hours and at the end they hang up on me , they are unprofessional seriously , I am going in circles with no assistance from anyone .I need my app urgently yet no one can assist me . I changed my contact number and just need to access my app . Simple but they make it difficult. I am going to change banks due to this poor service . Clearly I am not important to be assisted promptly.
