Costly incompetence

I went to the Nedbank branch in Prospecton to transfer funds from my cheque account to my bond which is with ABSA. The consultant named Dudu who was assisting me made a mistake and transfered it to someone else. R36 561.00 was wrongly transferred by Dudu to Mr Shezi who is with FNB.I immediately saw the mistake and confronted her about it as she had transderred it to an existing beneficiary. I then requested the manager to intervene and they called that beneficiary who then said they would transfer the money back the following day. I went back on the 2nd of August to check but nothing had been transferred into my account. The branch manager Ms Vanilla and Dudu tried to call that beneficiary Mr Shezi but he did not answer the calls. The same evening I called him, he advised me that he will reverse only R30 000 reason being that his debit orders have consumed the R6561 and the remainder will be paid end August. To my surprise even today nothing showing the reversal of R30 000. I am left with no money. This is my hard earned pension money and i trusted Nedbank and its employees
