MFC Assisted Sales department

I am extremely disappointed with the service from AVO which is a Nedbank department in the sale of my vehicle to a dealership which I have received the best possible price for my vehicle. I have done everything I had to do but someone in that department is dragging their feet. Can the Assist sales department of Nedbank MFC start doing their damn job. How do you call me on a Tuesday and then contact the dealership and then when it’s the Thursday on the day we agreed I should hand over the vehicle then Assisted Sales department ghosts me the whole week. I waited over 2 hours on the telephone with screenshots of how long I had to wait and still not speak to anyone ????!! Get your house in order. This is part of customer Service after sales !!!
