Absa fails to deliver after multiple calls and emails

Being an Ansa client myself, I am shocked to see the service my husband has recieved since last week Wednesday. He has a buyer for his vehicle and has been sent from pilar to post to get his settlement letter out of Absa. Even promises that your escalation department's manager will phone him, Anita, has not come to fruition. Every person promises by this time today you will have your letter, to date, nada,nothing not even a promised call back. He is Mr PA Venter, contact number ***. PLEASE can this be sorted out? Seriously, we will lose the buyer and it will be a direct result of Absa not sending a simple request, settlement letter.....
