Terrible service to try and close NEDBANK account

After I verified my settlement amount on call centre number *** (after I was on the phone for 15 min on number ***given to me by the branch), paid it and received sms from NEDBANK indicating payment received (10h07 am), I received a sms (13h07 pm) that a notice of demand was issued and sent for payment on the exact same account. Furthermore, when calling back on ***, I was on hold for more than 10 min. I have taken screenshots of the issues mentioned above as I am terribly agitated and disappointed.
