FICA Documentation

I app**** for financing when buying an additional property and Nedbank was the first bank to respond with approval of my application. From then onwards, stuff went wrong. To such an extend that my transaction had to be withdrawn from the deeds office because Nedbank declined my ID as FICA proof. But nedbank used the same ID to open a current account for me. Fazila Variawa from Nedbank is costing myself a loss in rental income and huge inconvenience to the seller. Nedbank should NOT employ people such as Fazila Variawa for she will cause Nedbank to loose clients. Please let me know what actions are being taken to rectify this and specifically what actions are taken against Fazila Variawa.
