Disappointed new business account client

In August i opened a business account at Nedbank assisted by Mthandeni, to which he did a great job. i was happy with his service. I was then assigned a business banker by the name of melissa whom since the inception of my account has never reached or called me to link my business account to my internet banking.

I called Nedbank on the 1st to follow up, and the lady who was assisting me said she will notify melissa to give me a call, today its the 3rd, i still haven't received a call from her. I don't want her as my business account assistant can a serious person who is committed to their work be assigned so i can get linked. I need to access my internet banking.
