Team leader and agent without customer care skills

On the 10-2015-07 (15:15) I called Nedbank after my bank advised they are debiting my personal account. First I don't have any product from nedbank. So when I phoned Nedbank to get clarity on who gave them permission debit my account. First thing their agent Xola said \ your bank is too quick to push the blame to others". When I ask him to check with the reference number if Nedbank is debiting my account he refused and told me to address it with my bank. He said\"" he can't divulge their clients details\"" when their client is debiting my account without my permission. He didn't even to bother to check if the debit belong to them"
