ABSA - no response and constant messages left

I have been an ABSA client since i started banking, for approximately 16 years. I app**** for a personal loan on Friday (10/05/2019) and received a system generated sms immediately saying the loan was provisionally approved. By end of Monday (13/05/2019), I had not had any feedback. I called the lending number (***) and spoke to Bongani who was very helpful and advised that the loan takes 1 to 3 working days to approve and she added a note on the system to ask the lady dealing with my application to call me. On the 3rd working day (5 days later), Tuesday (14/05/2019), by 14:30, I had still had no feedback. I called the above mentioned call centre again and got through to Bongani again. After answering the security questions, the call was cut off and no one phoned back. At 15:00 still nothing. I then called again and got through to another lady. She made me hold on the phone whilst she walked to the lady dealing with my applications desk which I appreciated. She then returned to the call and said the lady will phone me by cob today (14/05/2019). Surely this is not the way to deal with a long term client or ANY client for that matter who wants to do business with you. I have app**** for loans with other lenders and had the most terrific service and the money was in my account within an HOUR of submitting my online application. This is ridiculous, I cant even get someone to return my call. Please can someone contact me regarding my application.
