Stinking Service from Nedbank

On Monday i was advised that i qualify for a professional banking account. I was transferred to a consultant, and did an application. After that everything went silent so i called in on Wednesday, and was told its with the credit department and il get feedback within one hour. Then i heard nothing. Today i called in again and held on for half an hour and someone promised to get back to me but there has still been no feedback. The service is unprofessional. Im am very unhappy with the way i am being treated. Nobody returns calls or provides feedback. Its like no one cares or wants to take responsibility for their work.
