One and a half years of trying to open a bank account and NOONE CAN HELP ME!! SERIOUSLY NOONE KNOWS WHAT THE PROBLEM IS!!!!

For a year and a half now I've been trying to open a bank account and keep getting errors or a message that my application was already submitted. I went through to discovery because the one error was that my ID couldn't be verified. I then went to the home affairs at the Discovery building where they told me there was no problem with my ID verification. Discovery then told me to try later on the app and it will work. It didn't. Since then I've been told several times I can only register on the app, and every time I try I keep getting an error. Last week I was on the phone almost every day with several discovery people telling me different things on how to get it to work, or not knowing at all why it wasn't working. None of the solutions worked. I had two discovery agents promise they'd get back to me and I did get two missed calls when I was in a meeting, and so I called back the number and spent almost 15 minutes on the phone trying to figure out who called me, just to be told it's impossible for them to know who called me. I also didn't receive any message or email so have no idea who called me which is a major ball ache as since Wednesday no-one has tried to get hold of me again and I'm certain no-one will, which means I now have to go through the process of getting hold of them again and getting promises they will call me back and hold fingers crossed that when they do call me back I won't be busy or in a meeting, otherwise I will need to repeat the process AGAIN!!!!!
