Too many idiots

I'm trying to register online for Nedbank ID.<br> Step one, enter South African ID number. Done.<br> Step two, confirm mobile number. Hmmm, not my number. So I call Nedbank as My number has been the same for over 10 years, and I would like to know who changed it with what authority. Nedbank confirm my number and surprise its my number. The web site however has a different number. <br> I am then advised to go to Nedbank with my ID and change my number from what it is to what it still is, how dumb is that?
