Standard Bank Rosebank business banker cannot get the attorney accounts correct AGAIN

We are a firm of attorneys who have Sec 86 3 investment accounts with Standard Bank. Standard Bank has unilaterally changed the name of one of the accounts so that the clients name is no longer on the account. We did not request this to be done. I have been corresponding with Funekile Kumalo and a Johnny Barnard of the Rosebank branch who do not seem to be able to either look at the documents sent to me before they are sent, nor understand what the problem is. This has been going on for over a week now and despite asking that the account be corrected, Funekile continues to send me that same incorrect statements over and over.
