ABSA Personal loan

I took personal loan with ABSA. Then got enough money to settle the account just 3-4 days before the debit order date. The gentleman who was helping me with settlement amount told me to do the payment and send the proof of payment. I did. debit order date came the money went through. I sent messages no respond. I went to the bank I bank with they were unable to reverse that debit order, and they asked me to visit phone ABSA bank. I eventually phoned the consultant said she is able to see the settlement amount I paid and the account is paid up but she can't see the debit order amount. while still speaking to her she hangs up the phone. I am frustrated
