Appalling Service

I am appalled by the service I have received while dealing with Absa Unit Trust for a late Estate. We have been dealing with this case since last year august and we have reached no ending. The department asked for a confirmation letter of an estate account which had to be opened by Standard Bank ,which we have given them, they refused it claiming that it was a business account and not and Estate Late account, we contacted Standard Bank to verify the account and even had the stamp they (ABSA) still refused it. When I asked what was the problem the lady told me she cant tell now becasue she has to go home. I have never in my life recieved such disgusting service and I hope someone will help me because I am fed up with ABSA.
