Nedbank online banking blocks people over 60 after ONE incorrect logon attempt

If you are over 60 Nedbank online banking blocks your internet banking account if you input your login details incorrectly ONCE only (not the standard 3 attempts before being blocked). You then have to go to the branch to get unblocked. At the branch I witnessed a very helpful person being sent from pillar to post by whoever he tried contact to resolve this. More than an hour later, still nothing. So now I still cannot use my online banking while the very helpful person at the branch continues trying to find someone in the depths over Nedbank to sort this out.
