Reversal of difference in interest

On 8 June 2015 I went to First National Bank Vanderbijlpark Civic branch and deposited R70,000.00 to reduce the balance on my loan. When I called Direct Axis on 17 June 2015 to find out what the current balance is, I was told that the R70,000.00 I paid in was received and immediately reversed. The R70,000.00 was deducted from my bank account and thus didn't write back. I went to the FNB branch where I made the deposit and spoke to one of the Team Leaders, Mrs Teresa Havercamp. Mrs Havercamp informed me that my payment is reflecting in the Wesbank account and therefore should be allocated to my loan account. I called again Direct Axis and they said they will investigate. I received the Team Leader's detail - Faizel Hoosain, which until today, not once called me to find out the progress of my complaint. A gentleman, Rafiq called me and said the payment was traced and the reason that it wasn't allocated to my account was, the teller used the incorrect reference number. This is totally not true as the proof of payment I received from the teller at the bank, clearly reflects the correct reference number. I requested several times for an updated statement and
