Nedbank Cityview on Umgeni Road cannot help me to open their app on my phone for the ladt 4 days and counting.

Hi. I had a Nedbank app on my phone. I went to Nedbank in Cityview mall in Umgeni road to open a business account on Friday, 5th of April. The business manager at the branch tried to open a business account on my existing nedbank app. He had some problems and decided to delete the app and reinstall it. The Nedbank app could not be installed after many attempts. He called IT specialist who directed him to use certain steps and he failled. I then went to Windermere Centre Nedbank, who tried but couldn't install the app. This took the whole day from 9 am to 3pm. I went there again on Sat., 6th at 9am. He tried again and failed using different logins and creating new passwords. I stayed there till 1 pm and the branch was closing. He phoned IT and they gave him a ticket number saying someone will sort it out. On Monday, 8th April at 10 am I went back to the branch and the business manager and the branch manager tried to help, but failed to load my app on my phone. I spent about 4 hours there and was told that he raised another ticket to solve my problem. I went home. At 3pm the business manager phoned me and said he knows the problem and I should go to the branch the next day at 9 am. On Tuesday, 9th at 9: 30am, I was at the bank. The business manager tried many things changing logins and passwords. This didn't help. At 12:30pm nothing was being solved and he raised another ticket and told me to come the next day. In total I have been going to the bank for 4 days and counting. All I want is to install the Nedbank app on my phone. They claim it takes 2 minutes to open a Nedbank app. This is clearly not the case and I don't know when this is going to be sorted out. I'm seriously thinking of changing banks because Nedbank is not paying attention to my problem.
