Did not do what I asked to do

<p>I went ot collect my credit card in October / November 2016 at Nedbank Bedfordview. I asked them to amend my cellphone number, which the consultant amended my number as a secondary number, which is not correct. When I called the call centre, they advised that I need to go to the branch to change it, why must I be inconvenienced if the consultant at Nedbank did not do what I ask. all I want is for Nedbank to change the secondary number to my main number, surely it is not that difficult</p>
