City of Cape Town service delivery...what service delivery?

The City of Cape Town municipal accounts department is a sham. The behavior experienced when trying to resolve an issue of accidentally paying an old account and then getting a statement of the old account with the credit, but not being able to action an inter-account transfer even though all information requested was provided. When I try to phone them to sort out the problem, they either hang up or tell me to ring the other number (***), which incidentally when you ring them they tell you to ring this number ***). As a citizen of Cape Town, how long do we need to put up with this poor level of service delivery?
