UNDERHANDED AND ********* PRACTICE.

I was contacted by Mbali Mngcuna on the 11/06/15 regarding settling my overdraft acc with STD Bank,the 17/06/15 i made payment to settle my acc before end of June15 as per our agreement,the settlement amount i was given by Mbali was a 20% discount on my ***-62 was pd into my acc to settle it.I have been to STD bank 3 times to date trying to have this issue settled,the 2nd last visit i made was on the 11/07/15, i was told that my settlement amount would be paid to me in full within 3-5days,this has not happened to date and my acc is still inactive.The 23/07/15 i was told that because the money that got paid into my acc was not paid by me directly and that it came from the SARS acc that the settlement was invalid, such terms had not been part of the initial agreement and had never been mentioned prior.That is my money and i chose that it be paid into my STD bank account in order to settle the account as agreed with Mbali Mngcuna on the 11/06/15.This is the 2nd strategy STD bank is trying as initially they told me I had not paid in time which was not true.I emailed Mbali regarding this issue and have not heard from her and it has been 7 days since my email to her, just silence.
