Unauthorised debit order Nedbank

Nedbank debited an amount of R175.00 for a Maintenance fee and when I phoned in to the call centre I was informed that it was an error and I will have to go into the branch to have it corrected. It took 2 attempts and a very long wait to actually speak to someone at the call centre. What bugs me is that it costs the client more in fuel and calls to have the banks error rectified. I find their nonchalant attitude towards errors like this very concerning. I requested the telephone number of the branch at Table Bay Mall and was informed that a branch of that name was not listed.
