Rude Branch Manager (Idris)

I went to Nedbank Woodmead today to get assistance with the re-structure of my bond. There was not a lot of people in the branch but 2 consultants where helping 1 customer and we were just sitting and waiting and waiting. After waiting more than an hour in an empty branch my husband and I expressed that we have to get back to work, is it really necessary for 2 consultants to help 1 customer?? Then an extremely rude manager screamed across the bank at my husband and my self. My husband told him that we are customer how does he speak to us like that? He came marching over to us, pushed his hand in my face and told me that we must just leave his branch and we can forget about our re-structure. He told us that he will call both my and my husbands employers. My husband told him that we will lay a complaint and wanted to take down his details. The branch manager grabbed my husbands phone out of his hands and refuse to give it back. The security came and he still refused to give it back. The branch manager tried to give the phone to one of the consultants but she didn't want to take it and it was clear she was uncomfortable with his behavior. We manage to take down his name (Idris). I walked out and called the Nedbank call center. My husband was still inside trying to get his phone back. My husband came out a couple of minutes later with his phone. I also googled Nedbank Woodmead and there seem to be other complaint about the Branch Manager (Idris) for rudeness also. Can this man please get some customer service training?
