Standard bank can't process my APPROVED loan.

I called standard bank on a Tuesday morning in order to find out if I qualify for a loan, I had an amazing customer care experience everything was approved I was really glad I asked how long does it take to process? The agent said by Friday I was okay with that no problem. I then received nothing I called again and spoke to another agent asking what is happening he said it was approved and he the latest will be on Monday I said no that's fine I don't mind. It's Wednesday it has been a week I called yesterday the female agent said she will be emailing them and they will call me on Tuesday which was yesterday. I received no calls what's so ever I'm still waiting on the funds and I'm disgusted how standard bank can lie to their clients. I feel like changing banks because this is not the first time standard bank **** to me and I'm actually really disappointed.
