Taking standard bank to the lawyers

I did an application on the 7th of Jan for an RCP. I was approved and I had a whole lot of issues which I resolved as the branch submitted my documents incorrectly. I was then phoned to be notified that they have received everything, after I had to call in first. A few minutes later the consultant reverted saying they will release the payment. She then phoned back a short while thereafter saying they experienced a system error and eventhough I am approved the funds could not be released and I.T. will look into it. Today is the 9th of Feb. Still the payment has not been released. I know about CPA, Standard Bank is really disappointing and I am not leaving this. I have seeked legal advice as I have proof of approval as well as voice recordings on my phone of confirming that I have been approved and funds will be released. I am done calling after the consultants and sending e-mails that do not get responded to. This bank wasted my time, effort and my money!
