ABSA frustrating service

I paid money into my ABSA savings account with the intention of using that money to settle my ABSA personal loan on the 27th of March 2023. When ever i try to now transfer the money to the loan account in order to close i get an error on the banking app. I have also tried to get someone at a branch to help with the transfer with no success. I have now spent 4 hours(over 2 days) at branch and spent 2 hours on the phone trying to get this matter sorted out with no success. This now been really frustrating as i just want to be able to settle my personal loan and move on if with my life. If you don't want to allow me to do this settlement just at least allow me to return my money to my standard bank. I am trying to be a good customer by settling my loan early but you guys are making it super difficult
