Poor service and feedback

Good day, On 29 December 2021, I app**** for a personal loan with ABSA. I was provisionally approved by the system. I had to submit my documentation, which I did in full. On 3 Jan 2022, I was sent an email by Absa again to send my documentation, once again I have sent it. On 8 Jan I was sent a reminder again to submit my documentation, which I sent again. I have phoned the Call Centre 15 Times, and I am placed on hold or the call gets cut off, a total of 215min (3 hours & 58 minutes). I visited the branch, they refer me back to the phone as they do not deal with it, another call for 55min and no answers. So after 2.5 weeks and all the calls I made, still nothing finalized or even feedback. I do have automated email response with 6 different reference numbers. What should I do next?
