Rude agent

So sad for the mistreat I have received from one of your call centre Agents by the name of "Marikie Brummer" I had done a credit card application online and I was provisionally approved, When I called to follow up the consultant said I need to go to the branch to update my number yet I don't want to update any number , they have to of my numbers on their system and this consultant insists I update ,I'm still confused as to what should I update coz I absa has both my numbers that I use, she was really rude and arrogant
