Endless problems with nedbank call centre

I've been trying for days to sort out both my nedbank apps as well as internet banking. The contact centre keeps forwarding my call to the "relevant department". I can literally do nothing with these apps or internet banking because my cell number is not registered. My old nedbank app was locked without me even entering a password incorrect. Then I was advised to remove and download which I did and now when I want to activate banking it says my details are incorrect. It's one bad thing after the other with nedbank and all I need is to transfer money
