Nedbank-MFC very disappointing service

I dissapointed at the service received from Nedbank-MFC. It's been over 2 weeks and my approved finance deal has not been finalized, and I can't take delivery of the vehicle (which I urgently need). The rate promised during and the start of the application is now off the table with no explanation. My husband works for Nedbank and as his spouse they promised the same rate as staff. However that changed but because I need the car desperately didn't want to delay the application anymore by fighting it. And still the deal is yet to be finalised. There is no sense of urgency in the MFC staff at all. As a new client very disappointed with the service.
