The bank deactivate my profile without my consent

On 09/02 I called the Nedbank telephone banking to do telephonic transfer and then discovered that my profile number and pin got deactivated by someone from Nedbank Norwood. The consultant then said that she will arrange for the guy to call me urgently on 10/02, however, there were no calls. Then on 11/02, when I called the call centre again, the switch board direct my call to a team leader who when I explained the situation, just merely passing the buck and said that: \..the bank will not deactivate without consent..\". They did not even investigate anything and now I need to waste my time to go to branch to activate something that I did not consent to!"
