Total absent customer service

The worst bank to deal with must be Nedbank. I have tried more than two weeks to get an answer why my homeloan was increased due to recent activity I know nothing about and why my monthly payment is way above the outstanding balance. Visiting the branch was useless, they cannot help with homeloans., Spending hours phoning homeloans ended in 5 loops everytime with reception. The banker I was advised to contact rep**** once out of 4 efforts, the last email remains unanswered. The worst by far.
